# bcat's 60% Tsangan HHKB layout This is a Tsangan/HHKB (split backspace, split right shift) layout following the [traditional HHKB layout](https://deskthority.net/wiki/HHKB_Professional2) 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. ## Default layer  ([KLE](http://www.keyboard-layout-editor.com/#/gists/86b33d75aa6f56d8781ab3d8475f4e77)) ## Function 1 layer  ([KLE](http://www.keyboard-layout-editor.com/#/gists/f6311fd7e315de781143b80eb040a551)) ## Function 2 layer  ([KLE](http://www.keyboard-layout-editor.com/#/gists/65ac939caec878401603bc36290852d4))
