How can you do that???

i also remap caps -> ctrl, but have bindings for `fj` & `jf` in insert mode to exit back to normal mode, on the theory that you basically never have to type either of those letter combos (it has come up maybe twice in the five years i've had it set up). and even if you do have to type one of those letter combos, all you have to do is wait for ~half second between keystrokes and it works fine.

another long-time vimmer here, and i'm perfectly happy to reach up and hit esc. caps lock is a lot more useful as ctrl.

I use the one true keyboard and CTRL is already correctly-positioned. Once you ascend there's no going back.
