Subject: [PATCH] Add magic backspace to my layout (#2758)
* Add Haegin's keymap
* Potential improvements to the keyboard
* Add haegin minidox layout
* Add Haegin's keyboard to ergodox layouts
* Update Haegin's minidox keymap
* Add home, end, and page up and down
* Magic Backspace
Backspace still acts as control when you hold it down, but if you tap it
twice and hold it's a held backspace. Tapping it more than twice it
continues to act as backspace, but it deletes more characters with each
tap with the quantity deleted based on the fibonacci sequence.
* Switch to deleting words after 4 taps
When hitting backspace, after 4 taps this switches to deleting by word
because if you're hitting backspace that frantically you must need to
delete a lot of stuff. Holding backspace after 4 taps will delete words
in the same way that holding alt+backspace deletes words on a normal
keyboard.
