Log keystrokes

[eugeneotto]

This is kind of a random suggestion, but I sometimes struggle to adopt software like AeroSpace because when a keybinding doesn't work, I don't know if it's because:

1. The software is broken,
2. I have the wrong expectation for how it should work (I am new to tiling WMs), or
3. the key combo I used is getting routed to some other software (e.g. I was running Yabai+skhd as well as Rectangle when I first launched Aerospace).

Would it be possible for Aerospace to log the key combos it receives? This would at least help me rule out #3.
