Keyboard Chords with Hammerspoon

I love keyboard shortcuts. The less I have to switch between keyboard and mouse, the more efficient I (at least feel I) can be!

Problem statement

But there are only so many unique combinations of keys on a standard keyboard. Assume 26 letters, 10 digits, and (for now) 20 other characters, along with 4 ‘modifier’ keys (⌘ ⌃ ⌥ ⇧) that you can use in any combination of one or more. So 26 * 10 * 20 * (2^4 - 1) = 78,000 . Like I said. Limited. 😄

But we can do better!

Enter the Hammerspoon hs.hotkey.modal module!
