IMHO chording the 'j' and 'k' keys simultaneously [1] is a severely underutilized solution for escape.
Try it. You'll love it.
If you're going to rebind capslock to something — and this is particularly true if you're on macOS — rebind it to backspace. Capslock escape isn't useful outside of Vim. Backspace is useful everywhere, including inside Vim.
That's interesting. I'm a bit spoiled by primarily using Vim to write code and prosé in American English. Vim's digraph feature (Ctrl-K by default) has handled unicode char input nicely enough for me, but I wonder if the compose key could be of use when writing text in Japanese for example.
I actually meant to do it systemwide, for when you're writing or googling things not in English, or when you want to write a fancy ⅝. The day I have to start putting diacritics into computer code is the day I quit programming:)
I think it's no good for Japanese, but I know very little about Japanese input. Romanji is still Japanese, right?
