@7:02 how did you get "forall s a" to populate in the right spot on the lines below with one motion?

[@andresloeh]

"Visual block mode" in Vim, basically selecting a rectangular region at the beginning of all the lines, then insert at the start of every line in the block with `I`, see e.g. neovim.io/doc/user/visual.html#v_b_I

[@well-typed]

Using "Visual-block Insert" in (Neo)Vim, see neovim.io/doc/user/visual.html#v_b_I
