C-[ is the same thing in Unix. I haven't tried it on a Mac though. But if you're using vim (mostly where I hear this complaint) use C-[ (actually just use it in vim anyways because who wants to lift their hand up to do such a common movement?)
e.g. Ctrl-o to pop out of insert mode for 1 command only.
or
ctrl-w: delete the last word.
ctrl-u: delete to the beginning of the line.
ctrl-d or ctrl-t: change indent level.
ctrl-h: backspace without leaving the home row.
ctrl-m: without leaving the home row.
I do use most of those ctrl commands btw. I didn't know about ctrl-o, so thanks for that!
My little finger is much shorter than the rest but moving it a few mm to the left is easier than a large jump to the bottom of the keyboard for me.
For example, I use tmux a lot with ctrl-a.
A small movement of the hand left, jumping my little finger onto control (caps) and using my ring finger on A works really well for me.
Btw the first thing I do on getting a new mac is map the right alt key (or enter key back in the day) to control.
I hate having to press both keys with one hand for Ctrl key combos (ctrl-a being the only exception).
What? Have you tried this feature at all? If you map Esc to Caps Lock in Mac OS, the light indicator never turns on, and you don't enable caps lock when you press that key.
Or do you mean that this is what'll happen if you use a different computer? In my experience that's not a problem at all. Muscle-memory can be made context sensitive. I use two different keyboard layouts (dvorak and qwerty), two different key arrangements (staggered on my laptop, grid on ErgoDox), Esc mapped to Caps-Lock on my home laptop, completely different key mappings on my ErgoDox at work, and still I have very little trouble using a Qwerty keyboard with standard mapping if a use a different laptop. I'm probably a bit slower, but that's not really a problem if it's a computer I don't use that often.
Edit: I do notice that pretty much everyone that does the caps remap is using OSX. Is this because most people are using macs or just because macs have different behavior? Either way, I'd rather use a vanilla command than a remap if efforts are basically the same (my pinky rests on shift anyways and it is easy to contract my finger. I also use ctrl-backspace when typing in HN and other forms).
It's a key that's drastically oversized compared to it's barely measurable amount of regular use.
