bcat's 60% Tsangan HHKB layout

This is a Tsangan/HHKB (split backspace, split right shift) layout following the traditional HHKB layout with a few changes:

  • The Delete key is mapped as Backspace (HHKB DIP switch 3).

  • The Alt and Super keys are swapped to put Alt directly adjacent to the spacebar (HHKB DIP switch 5).

  • The left Super key is replaced with another Function key (HHKB DIP switch 2). Unlike on the real HHKB, this key triggers a different Function 2 layer. (This also helps prevent accidental Super key presses while gaming.)

  • The Function 2 layer contains reset keys, RGB underglow and backlight controls (in place of the arrow and navigation keys), and media controls (centered around the ESDF cluster).

  • The Function 2 layer also has the F1-F12 keys mapped just like the Function 1 layer. This is a concession to gaming because it enables these keys to be easily typed with the left hand, without taking the right hand off the mouse.

  • The leftmost and rightmost bottom row keys are mapped to Ctrl rather than anything more useful because most of my Tsangan PCBs actually have HHKB plates and/or blockers, so there aren't switches installed in those positions.
