My pinky starts hurting when I hear emacs.
1. Remap Caps Lock to Control and press it with my ring finger rather than my pinkie when possible (e.g C-a, C-s, C-d). I still use my pinkie for C-g or C-r, but diminishing the number of times it is used was very helpful
2. Map more keybindings to use Alt rather than Control.
I've been using Emacs keybindings for a really long time now, but I think I could be convinced to try the Ergo Emacs keybindings. My only worry is that my keyboard is French Canadian (with dead keys), so I'd probably need to first start by remapping a bunch of shortcuts.
A little surprised you've remapped capslock to ctrl, but also remap keybindings to alt. IMHO, alt is more of a stumbling block than control, because you pretty much have to take a hand off of the home row to use it. I find pressing capslock with the pinky not to be a problem, and if anything, have really appreciated a Steve Yegge tip of binding C-x, C-m to M-x (as well as C-x-m, for ultra laziness.)
(I'm quite keen to try it some day! Love your work in the Emacs community by the way.)
