Emacs keybindings like Control-x Control-c don't work for me on regular keyboards. They work just fine for me on ortho keyboards with an easily accessible control key for my right thumb.

Ortho keyboards got me in the habit on using modifier keys on the opposite side of the keyboard from the shortcut key. On a regular keyboard, I'll type Command + c with my left thumb / left index finger with an unergonmic movement. On an ortho keyboard, I use my right thumb + left middle finger for the same motion.

For Vim, I started using Control + c to escape with ortho keyboards, which keeps me on the home row.

None of these are huge productivity gains. But a fun way to shock your brain and to stay sharp.
