Key combinations

Is there an easy way of detecting key combinations, similar to how vim key combos work?

I'm guessing I can implement something myself by recording the time between key presses and all that.

The use case is to allow more complex keybindings in a program that are easier to remember.
Prefixing key combos with something like vim's `` key, or global actions with g.

The issue names no file, test, or entry point, so begin by locating the repository's keyboard input and keybinding handling. Done would mean a documented, tested way to recognize multi-key combinations or a leader prefix for more complex bindings.
