Experimenting with @susam's Devil package to streamline standard key bindings when using Emacs inside of Termux on Android.
It's useful, cleverly designed and has some nice benefits like its own key repeat mechanism since you can't hold comma down as a modifier key.
I like it better than god-mode because it doesn't require you to keep track of what state you're in, just press the comma key anywhere and follow its translation rules.
