I\'m a Mac user and I\'ve decided to learn Emacs. I\'ve read that to reduce hand strain and improve accuracy the CTRL and CAPS LOCK keys should be swap
I've created a fairly comprehensive set of bindings here for use outside of Terminal.
Personally, I can't use the mac laptop keyboard due to the absence of the right control key.
Instead, I have been using the Microsoft Natural Ergonomic Keyboard 4000 for over 7 years: it's got really fat, well-positioned Ctrl and Alt keys, and after downloading its drivers the "Start" and "Application" keys are trivially remapped to the Mac Cmd key, which is also fat and easily depressed.
To avoid emacs ergonomic concerns I've trained myself to use Ctrl, Alt, and Cmd the same way we use Shift - depressing them with the hand opposite the one typing the actual key. (That is, I just leave Caps Lock as is.)
