Great advice. Hitting modifier keys with the thumb is how Emacs is meant to be used, in my opinion. It's the strongest finger, after all. > For Emacs users, common wisdom is to swap control and caps. This is terrible advice and it causes so much unnecessary pain. - The pinkie is the weakest finger. - Stretching sideways is a terrible movement. Try it several times and compare it to moving a finger up, or curling the thumb. Stretching sideways should be reserved for infrequent actions -- hitting a modifier key is much too frequent for Emacs users. - You should have modifier keys on BOTH sides of the keyboard. Using Emacs with just one Ctrl key is just... awkward. There are so many common keybindings (like C-x C-c) that are difficult with this scheme. With Ctrl to the left and right of the keyboard, however, I can just curl my right thumb a bit and then press x and c. If you have RSI, maybe one of your hands is overworked (i.e. you only use Shift with one hand). Big opportunity for improvement there. Unfortunately not all modern keyboards have modifier keys on both sides of the keyboard, so you definitely have to watch out for this when e.g. buying a laptop. With the key system you suggest, Emacs bindings are even better even than Vi modal editing, in my opinion. Pressing/lifting a thumb is much easier than changing editing modes.
