[@rafaelrafaelrafael]

You missed the ADM-3A, which is the reason why vi(m) uses hjkl as cursor keys. That was so influential that many modern software still supports those (from memory: Gmail is a good example, where you can use j/k to go up and down your emails)

[@travcollier]

yep. Vi was 1976 IIRC I do prefer an inverted-T set of keys though.

[@thezipcreator]

I always wondered why vim supported those as cursor keys. TIL

[@travcollier]

Oh, FWIW, the trs80-102 cursor key layout actually matches vi (left,down,up,right)... Which is one of the most sensible one row ways of doing it IMO... Swapping down and up is arguably slightly more sensible, but close enough

[@thumbwarriordx]

There's something to be said about the basement wizard's deadlocked home row hotkey setups from those apps. The programmer ethos is very different from say a desktop artist's idea of how hotkeys should work. It's the difference between working all over your desk and locking your hands to the home row hell or high water.

What I love about the straight 4 bit is, there’s only twelve possible arrangements of those keys, and they managed to use *seven.* (There’s actually 24 but half of them have left and right the wrong way around.) The only ones missing are the interleaved ones (LURD, LDRU, ULRD and DLRU) and LUDR.

[@jeff__w]

Seems like they were operating with the implicit constraints of having the L and the R on the, well, left and right of each other, as you mentioned, and keeping the U and D paired together. So they really managed to miss "only" the LUDR. That’s a bit surprising because the L and U move the cursor back through the document while the D and R move it forward, so those keys might be paired “naturally” but I guess not.

[@I..cast..fireball]

LDRU is best straight 4

[@jonadabtheunsightly]

@@I..cast..fireball The most common straight-4 movement convention these days is hjkl, which is left-down-up-right (on a QWERTY keyboard; heaven help you if you play roguelike games on Dvorak). Although, except for vi and derivatives thereof, most of the software that uses hjkl for orthogonal movement also uses yubn for the diagonals, and at that point it's not a straight line any more.

IBM also made a ridiculously large 122 key layout with the Home key in the middle of the arrow keys, and *twenty four* function keys at the top of the keyboard instead of the usual 12. My local library had this layout on their public catalogue terminals and it was awesome! With all those keys it felt like being in control of something really important.

[@admirerofclassicalelectron2858]

It was used by the 5250 Twinax terminals for the AS/400 and later IBM i - strange but powerful machines. The user interface, the green screen, is based on function keys and their use is standardized (F1 help, F3 back, F12 cancel, ...). So 24 function keys are quite usable.

[@ShaunDreclin]

Interestingly enough windows still supports F13-F24, if you can find a keyboard with those buttons

[@wlocek369]

​@@ShaunDreclin SHIFT+F1 --> F13 SHIFT+F2 --> F14 ... SHIFT+F12 --> F24

[@daniel_kos]

​@@ShaunDreclin Then that opens up a mystery, because I don't think IBM terminal keyboards could EVER physically be plugged into PCs. I once got my hands on a free IBM model M keyboard and thought I'd hit the jackpot... but although it had a DIN plug that seemingly looked like it could plug into an IBM PC, the pins were spaced out very differently to prevent this. Then I found that Unicomp sells a reproduction model of the IBM 122 key keyboard with a USB interface; so I bought one. But the exotic keys on the Unicomp don't generate unique keycodes either! Disappointingly, they've hard-coded all the "cool" keys more like macros to simulate other key combinations that would work with some obscure legacy Windows terminal emulation software. So instead of getting a unique keycode when you press F13, your PC just receives "Shift+F1" and so on.

[@11FHS11]

I actually use one of those keyboards on my PC under Windows 10, works just fine. The bigger issue is the ESC key rather than the arrow keys, and actually I kinda like the placement of the home key as a programmer.

[@tylerroberts1276]

Being born after the IBM model M keyboard meant that I only knew the Inverted T cursor keys. It wasn't until I discovered this channel and classic computers, did I finally see keys that aren't the standard arraingment. Hearing about where they became the norm, and where PC cursor keys were like prior to to keyboards like DEC's LK201 personally is a very fascinating video in my opinion. Thanks for the history lesson!

[@toomanyinterests]

Some newer keyboards have a different cursor key arrangement, we have a Microsoft "Natural Keyboard Elite" ergonomic keyboard that has the cursor keys in the diamond arrangement. For a time it was connected to our PC. I thought it was really cool until I wanted to play a maze game from a CD-Rom. With the diamond arrangement, as well as the steep angle of the keys, I couldn't find or press the keys without looking at them. We switched back to the normal keyboard.

[@pastarhythm2762]

12:13 Many traditional dungeon-crawler roguelikes also let you use eight-way keys to move around. Since these games are turn-based, moving diagonally is very important, and you'll do it all the time. It's cool to see that a lot of other classic games used that configuration as well!

I find the C64 layout to be actually surprisingly decent, possibly the best you can do with only two keys. As a kid, I couldn't get used to them until I figured out the thought behind the arrangement: By default, you progress along the screen, with the key off to the side moving the cursor sideways and the other vertically; hold shift for reverse. That's how I explained it to myself at least, and once that clicked, I could comfortably use the cursor keys without thinking, it felt completely intuitive and natural.

I spent a lot of years with the IBM numlock style cursor keys, and I always used my thumb for down instead of my middle finger which would stay on the up key. Even now, I still find myself continuing this habit on the inverted T keys, and even when playing games with WASD if I'm in an area where I don't need to jump I'll find my left thumb moving from the spacebar to the S key for down.

[@tomothywalker]

Yep. My first PC was a Compaq Portable, and I was 4 or 5, so about the only way I could reach all four keys was using 3 fingers and a thumb. As the inverted T arrived, I continued to tuck my thumb up under my fingers in something akin to a pen grip as that's how my brain was wired to hit down (I have "hitchhikers thumbs" so perhaps that made it easier for me?!?). Interestingly though, with the advent of WASD controls, I move my middle finger up and down to move forward/back, with my thumb is permanently hovering over space (I guess from typing induced muscle memory). The funny thing is, I'd never thought about it until watching this video, and assumed everybody just used their thumb to hit down on the "arrow keys".

[@rogink]

Can someone explain why we still have numlock? If you have separate cursor keys why bother to make 8 4 6 2 cursor keys? It's really annoying trying to type numbers only to find the cursor moving around the screen!

Another interesting "arrow keys" tid-bit: With DOOM, you use the arrow keys for movement and the mouse for turning and shooting. But most modern games opt for the "WASD" arrangement instead. This actually relates to John Romero - he's left handed. He's a South paw. So, for him, it's actually intuitive to have your right hand on the arrow keys and then the mouse to the left of the keyboard. Being a leftie, that's perfectly natural to him, so he used the arrow keys. But most people are right-handed. And if you're right-handed, this means that your left hand is crossing over the keyboard to reach the arrow keys, while your right-hand uses the mouse to the right of the keyboard. This can actually be a little cramped. So other developers moved to "WASD" as it's more natural - for right-handers, which is the majority - to have their left-hand on WASD - on the left of the keyboard - and the right-hand on the mouse. Your arms are not crossing over in an unnatural position, so it feels nicer. Although, the best games are clever and support "WASD" or arrow keys, to let the player choose, based on their left- or right-handedness. Or, you know, just always include a "configure keys" option in the menu, and let the user sort it out for themselves. p.s. comment edited: It was John Romero, not John Carmack. I recalled incorrectly, but it's changed to be "the right John" now.

All DOS games of the shareware era used arrow keys and Doom did not have modern FPS mouse controls (mouse Y was mapped to move forward/backwards). I don't think Doom needs any special reason to use the standard control scheme. Even quake 1 had mouse look disabled by default and used arrows to control IIRC.

[@CakePrincessCelestia]

I started playing games like Unreal and Half-Life with the cursor keys back then, but quickly switched over to the numpad, shoving my keyboard further to the left. Reason? More keys for stuff and the absolute freedom to place my mouse comfortably. I had some scripted keybinds on the Alphanumerics that resembled the weapons menu of Half-Life and Counter-Strike. Wanted to select the 4-2? Just hit R. 2-1? Hit 2. 3-3? Hit D. But after that I switched over to ESDF, but quickly went WASD instead, because it was easier for me to find that gap on the CANTERLOCK key than it was to find the bump on F quickly. And only then I realized what probably only a very few do know: Ultima fricken Underworld had WASD, well kinda, in Nineteen fricken Ninetytwo, even before Wolfenstein was out! It actually was SZXC with A and D being turn keys without moving forward and W being the faster running motion. And since it didn't have mouse look (but mouse control for the whole movement pattern within the 3D window which works quite well, I only played them that way), you basically played it WAXD mostly if you didn't just use the mouse which was more granular. That game was so well ahead of it's time and to be perfectly fair, if you missed it, it's still worth playing today. But if you really need at least some _filtered_ textures on your polygons and nice effects in fullscreen 3D, you can try Arx Fatalis (in Arx Libertatis engine) instead, it's a similarly great experience.

[@r0kus]

An innovation of the Amiga keyboard is that the cursor keys would also function as mouse movement keys. It was a two-hand operation, though, requiring that the Amiga key be held down while you used the cursor keys for mouse motion. It wasn't ever a major feature, but if your mouse died, you would not be dead in the water.

Was it any better than trying to use a gamepad as a mouse? AT&T (and presumably Xerox/Olivetti) had the opposite feature, where a mouse could function as the basic four cursor keys.

Later in Fall '83 the cost reduced 800XL and 600XL were released for Xmas but dropped extra keys. However, functions were kept in the XL/XE OS. I found in an ATARI magazine of the time (Analog, Antic, or Compute!) an article how to add the function keys back by adding four buttons.

The story about DEC and the inverted-T layout on the LK201 keyboard which appeared in 1982 is interesting. I was an engineer at DEC from 1978 to 1992 and this my recollection of it. It wasn't the first time DEC used the layout (as far as I can tell that was on the VT71-T typesetting terminal that dates from 1976) but it had used several different layouts for cursor keys on its video terminals. The first was the VT05 (1971) which has 4 keys in a 2x2 square layout with up and down on the top row and left and right on the bottom row (IBM used the same layout on its 3270 series terminals). The later VT5x series (1975) had a vertical row of 4 keys which top to bottom were up, down left and right. Following on from that the VT100 series (1978) had a horizontal row of 4 keys which left to right were up, down, left and right. Although an internal standard for terminal keyboards had been produced in January 1980 it didn't standardise the cursor keys. In late 1980 development work was starting on several personal computers and a decision was made to have a common keyboard for all of them. It was seen that text editing tasks from word processing equipment would see the heaviest use of the cursor keys and much research and testing was carried out (I think it was done in the word processing group) on cursor key layouts. Many of the tests involved having people perform various timed text editing tasks with different cursor key layouts. Those tests showed that down and right was the most frequently used sequence and that the inverted-T layout was the most efficient and that is why it was adopted for the keyboard.

[@paul_boddie]

Thanks for the interesting story! I imagine that this work contributed to the DEC Rainbow having the same general keyboard layout as the VT220, instead of copying the IBM PC, and thus itself influencing the later IBM PC layouts.

How about the “WordStar Diamond”? Trivia: Since the Franklin 1200 (the Apple II plus clone) was basically purpose-built to run WordStar on it’s included CPM card, the numbers pad could be switched to cursor control and when in this mode, pressing the arrow keys on it actually sent the Control-E, Control-S, Control-D, and Control-Z key codes to move the cursor around in WordStar.

MSX was famous for their different cursor keys. I had a Gradiente MSSX 1.1, and the cursor keys were a rectangle, with diagonal lines dividing the 4 arrow keys.

Back in the day when I used to play Lego, Star Wars, Indiana, Jones, etc. I use the error keys for a very long time until they new arrangement WSND style. I had to learn that.

I remember in the 90s the standard for gaming was to NumLock off the numpad, and use the numlock cursor keys for games. And in the 2000s, it was to use the cursor keys for games, with the keys in the 6-key block above it, along with shift, right ctrl, return and backspace for other game functionalities. I didn't use WASD until the 2010s.

[@belstar1128]

Yea i played a lot of pc games in the late 90s but in 2001 i took a break from pc gaming. and i came back in 2008 but i kept trying to use cursor keys but games moved to wasd .also modern games require a mouse wheel and that is annoying for laptop gamers and hand held pc's. and wasd is annoying in my region since we use the azerty layout so i prefer the cursor keys. but most games let you redefine the controls.

[@daylightanimation]

I still don't use WASD in games... more comfortable with standard arrows.... luckily most of them allow you to change controls the way you want to

[@davidellsworth4203]

I'm one of the very few people who do not prefer the inverted-T layout. Since 1991, I've been using a Northgate OmniKey Ultra, which belongs in the category you noted at 13:26 in this video, with a cursor pad modeled after the way the numeric keypad works when NumLock is off (though there was also an inverted-T version). I use the numpad often to enter numbers, so it's great being able to use both that and the cursor pad in my preferred layout without having to toggle NumLock. But it does mean that no modern keyboard suits my needs, and I've had to keep buying OmniKey Ultras off eBay when too many keys get sticky/bouncy for repair to be practical. (Sadly I couldn't make the switch to an Avant Stellar, because while it was based on the Northgate OmniKey Ultra2, it only had an inverted-T model.) I have learned how to be more kind to my fourth OmniKey though, so it might actually last much longer than my previous three. (My first was the original Ultra, and starting in 1995, I've had an Ultra2 with n-key rollover; at this point, the Ultra no longer works, and two of the Ultra2 need repair - I'm using the third Ultra2.) Now while I can certainly understand why people prefer inverted-T, it is much more unfortunate that function keys being on top became the standard. Function keys on the left, with F11 F12 on the top row, is much better and allows function keys to be easily used by touch. I think function keys on top being the standard has actually resulted in far less software even using function keys at all in their default bindings, which is sad.

I've seen, back in the day, people play using the IBM configuration with their thumb on the 2/down key. I also missed the MSX cursor keys, which had an arrangement like the IBM, but in a square fashion (and were also often played by using the thumb on the down key).

Some old DOS driving games used the greater than and less than keys < > for left and right steering. I still play Geoff Crammond's F1 Grand Prix from 1991 (via DOSBOX) which uses < > for left and right and the A key for accelerate and Z for brake :)

[@AutPen38]

It was very common in days of yore for games to only use 4 buttons, plus one for fire/jump and it made ergonomic sense to use both hands for directions. e.g. left hand does up and down, right hand does left and right. In a bit of a chicken and egg situation, games started getting more complicated, with more buttons to press, around the same time that cursor keys became more commonplace and in the "standard configuration" (leaving the left hand free for actions like firing, jumping, picking up objects). As an old skool kind of guy, I preferred the old games that used no more than 5 keys but still used both hands.

[@caeserromero3013]

@@AutPen38 Me too. All the original old DOS games used to use the arrow keys. I seem to remember even later games like Wolfenstein 3D and Doom used the arrow keys. WASD was a more recent key configuration for things like Medal of honour and Call of duty. I think the main difference between the new shooters and the old dos ones is that aiming. You used to aim by moving your body, so just the arrow keys to move and the ctrl key to shoot, but COD type games have separate control for the weapons, so you move the person with WASD and move the sights of the weapon with the mouse, so a totally different dynamic. And some games even use the mouse to move the person too. I think when riding the horse etc in Assassins Creed, you press W to move forward but the mouse to steer right/left. I really struggled with that at first :)

It's amazing how that muscle memory laid down in younger years sticks around deep inside the brain; I'd spent hours coding on the Atari 800XL back then and so when I picked up the retro bug all these years later, it was effortless and I hadn't given it a thought, not till this video!

[@AutPen38]

I grew up with the rubber-keyed ZX Spectrum and had no problem playing emulated games with various configurations of keys (often A and Z for up and down, O and P for left and right) but it was really weird when I tried typing some BASIC, as I've got so used to modern cursor keys that it was very weird to be reminded that the Speccy didn't have any! (You had to press SHIFT and 5 for left, for example). It felt so weird that - with the emulator I tried, the cursor keys on my PC keyboard did nothing at all! I don't know how I ever programmed anything in the '80s without them.

[@-taz-]

I started on an XT clone that was a joint venture between Toshiba, Xerox, and Microsoft using an 88-key Xerox keyboard (and a made in Japan MS RJ-11 mouse that connected to the keyboard).

Being trained to edit text and draw PrtintMaster graphics at such a young age was always a benefit to me to the point where I can still easily outpace my long time vi expert coworkers.

I don't think it was rocket science which arrangement was better. Almost anything is better than the inline four. But things like ease of manufacture, space, and needing to not obviously rip off a competitor, got in the way.

[@Dranok1]

11:00 It's not a horrible arrangement at all: throughout the video up to this point you've insisted on using only your middle 3 fingers; normal users presented with this intuitive layout claw their hand and use the thumb for Down thus enabling smooth navigation and gameplay. A few seconds later you show us the Osbourne with it's slightly staggered cross: this was the optimally perfect arrangement! It allows the thumb to be used with less movement of the joint, far more comfortable for longer term operation (like an afternoon of gaming after school!) 13:35 And here you demonstrate the perfect use of the thumb! The IBM "AT" layout was the optimal evolution: the open cross instead of compact T allows you to _use your thumb_ with an even more relaxed hand position, the loose claw, far less RSI in that thumb joint!

[@litigioussociety4249]

I'm surprised you didn't mention WASD once in this video. Those are the intuitive letters to choose for a D-pad, and for some odd reason many keyboards would not allow you to input two cursors at once and another key, such as up, right, and zero on the number pad to jump and run or shoot. However, the software would allow W, D, and the zero to be pressed together.

When I went to the C=128, I was looking forward to the 4 dedicated keys. But... I rarely used them in the end. Being at the top made it a pain to use. So I kept doing the VIC/64 keys until I went to the Amigas... of course the A500/2000/3000 inverted T worked great.

[@-taz-]

Wasn't that in the original MS Ergo keyboard (Elite)? If so, I had that, and I really liked it because it shrunk down the inverted T keys, letting me put my mouse closer to my keyboard. It was perfect for me since I use NumLk/keypad cursor keys instead of inverted T. And then the later MS ergo keyboards that reinstated the inverted T always bugged me.

[@CaptainCaveman1170]

I hate those tiny half-keys too, but I understand why they do it (it preserves the nice rectangular shape of the keyboard). But, the more recent trend is far, far worse in my opinion. They are now making the up/down keys full size...but shoving the "up" key right around where your finger expects the shift key to be. I absolutely hate it, and it's a deal breaker for me. But I doubt Gen Z cares, which means the keyboard layout that I prefer is going away soon (and already is becoming harder to find on low/end or "casual" laptops).

[@paulguk]

It's a shame you didn't discuss modern laptops. I think there's an annoying trend there recently where manufacturers are designing keys to be visually pleasing rather than tactile. A lot more use full size left and right cursor keys, but half size up and down. As a developer it drives me crazy as I use the cursor keys a lot, and my fingers struggle to find where they are without having to look if I can't differentiate between them because they're all the same shape rather than the traditional inverted T. I wish more people would mention the keyboard layout when reviewing laptops. It's the single most annoying issue that can make an otherwise great laptop almost useless to me 😢

This is a good trend. Looks like the MSX configuration, except the up and down keys are too small. I would like to buy such laptop (never seen one). On MSX you could press two buttons at the same time to move cursor diagonally, even in text editor. If you had two opposite buttons pressed at a time and released one, the other would activate. The author it seems intentionally skipped MSX so to make IBM PC/Wintel look good.

the guy is living under a rock though. Any non-gaming laptop that is built after 2015 is almost guaranteed to have stepped back to a worse arrangement of the arrow keys, where up and down is overlapping. This should not be a thing on devices that are 14 inch and up. You can thank Apple for this since Dell and HP just copied that idea and then everybody else followed along with it blindly.

[@carlosgd]

missing mentions: - the already quoted in the comments about the MSX constellation and its 1000's combinations of cursor keys (msx is rare in US and 8bg tends to "forget" non-US systems frequently) - the original amstrad CPC is another example of "crossed" cursor keys, with the "copy" key in the center of the 4 CK's and an odd placement in top of the numpad. PCW also uses a similar arrangement, crammed into the numpad. changed later in the 6128 in favor of inverted T arrangement (crammed with the "function" keys in a numpad layout) - the modern tendency to use WASD for "cursor" keys, to use with the left hand for movement, and combine with mouse with the right hand for view and rotation, most predominantly in games.... and its ultimate tradeoff of, decades later, start selling again PC keyboards that are not "extended" ones, but cruched ones, which some of them not only does not have "numpads", even some of them dont have inverted T cursor keys! - in many games in 8bit systems (essentially in the zx spectrum, but also in others) using OPQA, or some other combination like AZNM, for ortogonal movement. nice recap video. :)

The Apple ][ with an Autostart ROM had cursor keys of a sort but they were not labeled. If you hit ESC then I, J, K, & M turned into Up, Left, Right, and Down respectively until you pressed another key like SpaceBar to cancel that mode. ESC and A, B, C, & D also moved the cursor to A-advance, B-backspace, C-go down, or D-go up but you needed to hit ESC prior to each individual move.

@@kc9scott Nope. ESC keys were in the F8 monitor ROM since 1977. I remember using ESC-D from the monitor in 1978 when Applesoft was on cassette. Look at the disassembly of the F8 ROM and you'll see that it has nothing to do with Applesoft. It was specific to the RDCHAR routine at $FD35 which was called by the GETLN routine at $FD6A. The original F8 ROM had A-advance, B-backspace, C-go down, D-go up, E-clear to EOL, F-clear to EOF, and @-cls. The Autostart ROM added the modal IJKM bit. Every program which used GETLN or RDCHAR included ESC key support.

Maybe you want to check MSX machines, they mostly have a square/diamond layout and some of them are really weird

[@owlstead]

Yeah, I learned to love the square arrangement on my VG8235, although I currently would prefer the inverted T, or the Mod + JKLI on my current UHK.

Works for me. You can easily move 4-direction game characters around and never miss a beat. I was aware of it too, wondering why they chose this for the Fujitsu keyboard. The right choice. Thanks for the upload.

There's basically two things I think you forgot to mention about the inverted T. Firstly the most important one is that it wasn't really popularized by the IBM Model M on any sort of PC, but rather it's use on the IBM RT PC. IBM had previously experimented with different variations of the Model F they finally got the IBM 4704 F77 which turned out to be the basis for the Model M on the RT PC which was later lent to the IBM PC AT and later on to the PS/2. Secondly, even though the RT wasn't that successful, it forced SUN to move from it's Type 4 keyboard which was PC-esque, to the Type 5 which is the biggest keyboards I've ever used. Silicon Graphics stuck with a Model M type, which was the reason Apple went forward with that same design for it's extended Keyboard ADB keyboard. Even NeXT on 1989 offered a similar keyboard, albeit without all the function keys which looks remarkable similar to the Mode M. So why did the Model M modeled the UNIX world? Well you said it yourself. Most workstations were trying to extend the VT220 which had the 8 region design (9 if you consider the lonely Esc key on the left side). The PS/2 was really a confirmation that the RT was right and everyone needed 12 function keys and a separate block for the inverted T and the cursor control (Begin End, Pg Up Pg Down) thing. For me the 101 keyboard has always been the RT keyboard and it was on the RS/6000 that I got to use it extensively. Ironically, the big RS/6000 were accessed using a terminal and the one of choice was the elegant ASCII Display Station IBM 3151 which had a Model M. www.computinghistory.org.uk/det/4805/IBM-RS-6000-Model-550L/

My wife and I always use the curser keys but my kids both use the "ASDW" which is standard for a lot of games. I find that I have to shift the keyboard to the left when gaming, but that's what I do. Even weirder to me, my cousin uses his mouse in his left hand. I'm in my 50's and he's even older.

[@awmperry]

Ah yes, the olden days of cursor key movement, key-bound vertical look, and fire bound to LCtrl. I’ve got a vague memory of Duke 3D defaulting to that in its early shareware days, but I wonder if maybe that wasn’t among the last big games to use it?

[@marasmusine]

The ZX Spectrum, like the Timex 1000 in the video, had cursor keys in a row on the 5 6 7 8 keys. You just got used to playing games like that, you needed both hands though. You would use your right ring finger to press the fire button on the 0 key. The Sinclair joystick interface was mapped to those keys.

[@tendrosstoodross2976]

Sinclair right hand joystick port was mapped to 6789 and 0 not the cursor keys.

[@AutPen38]

Due to my lack of joystick and my love of Psion's 'Match Point', I trained myself to use 5 keys in a row on the rubber keyboard. It seems mad to think of it now, but - as a kid - I could play a two-player game with a friend with four hands pressing all the number keys on the top row of the little keyboard. I would use 1-5 and my friend used 6-0. As I recall, if you held down a couple of keys, some of your opponent's keypresses would be ignored, which meant it was quite easy to serve an ace! After learning the "5 in a row" alignment, I often used that configuration for other games that allowed keys to be redefined. I often used QWERT for left-right-down-up and fire. Is my mind playing tricks, or was that also the default layout for early games by Ultimate Play The Game? I feel like Atic Atak might have used that configuration.

[@player1_fanatic]

Fun fact, I still use original IBM-PC layout for cursor keys even today, since my first home computer I started with was IBM PC-XT with same layout. And all modern PCs still support it as long as I turn off NumLock key. As extra bonus Pg Up/Down and Home/End are all on convenient places, and as long as I pick up any keyboard or laptop with numpad I can use the same layout I learned over 35 years ago, as a kid.

[@-taz-]

Same! This is the most important keyboard fact, by far, if you ask me.

[@widicamdotnet]

Me three! Started on an (outdated at the time) Amstrad PC1512 that had a keyboard similar to the Model F. Now nearly 30 years later, I still revert to using the numpad arrows whenever and wherever they're available, especially for text editing and coding. When I'm using my partner's ThinkPad, we're always fighting over whether NumLock should be on or off :-)

[@rlovemaths]

Nice video! For me, the Commodore 64 had the best cursor keys ever. Unlike what is shown in the video, I was using the left shift key to move the cursor and this was very efficient: with just three fingers I could move all around the screen very quickly

[@TPIR_Fan_1972]

Good episode. This is the kind of stuff I enjoy seeing on this channel.

[@cosmefulanito5933]

MSX got things right from the start. A computer forever forgotten by this channel.
