It's actually one my favorites, just remap it to CTRL or something similar and bam! You have one of the most ergonomically accessible modifier keys, much better than stretching your pinky all the time.

The first thing I do when I get a new computer is mapping caps lock to esc for vim :p

It's more standard (in the sense that the Sun keyboard did this) and more useful to map it to ctrl. You can use ^[ to get esc.

I found it pretty useful to do both. A quick press is esc while holding it down is ctrl. I do find caps lock useful enough to keep it around still, so hitting left shift + right shift toggles that.

TIL! I'm so used to binding it to esc but maybe I'll give ctrl a go

I use it for drop down terminal, pretty useful.
