You know what would be amazing?
Some kind of OS-level overlay that would let you use vi movement and editing keys in any program.
I'm talking about going beyond something like having custom QMK keystrokes to use hjlk as the arrow keys (which is super neat, to be clear). I'm talking about a little pop-up that lets you enter something like A and it hits the End key for you, or Rapple^[ and it types 'apple[del][del][del][del][del]`
Am I the only one that thinks reaching for those special keys on the keyboard is a total drag? Especially on laptops? XD
