I don't know about other Vim users, but these incantations are foreign to me. I'd do most of it with "." or macros.

Also like, I love that this person loves Kakoune, and IMO that's sufficient. No need to be like "look how garbledy this Vim bullshit is".

In general this author is comparing robust vim solutions with golf-style solution in Kakoune (i.e. assuming the example is the only thing in the buffer).

I'm not saying multi-select and Kakoune's predicate-then-verb (instead of vim's verb-then-predicate) aren't cool, it's just that he has very strawman comparisons because the vim solutions could often be phenomenally simplified if the same assumptions were made in the comparison.

OTOH, I learned some cool Vim features from those incantations that may be handy in a pinch someday.
