I use vim and have caps lock bound to control. I use Ctrl-[ to switch to normal mode and ctrl is so much more useful outside of just vim.

I remapped jj to esc, for what it's worth, so I don't have to reach for anything. I'm one of the Capslock-as-ctrl people as well, and a vim user.

I have done no remapping but Ctrl-[ is very good for my wrists.
