The idea of this is pretty simple: base layer has four action, two of which (the outermost)
|
|
are regular keystrokes on tap, and a momentary layer switch on hold, sending you to layers 1 and 2.
|
|
|
|
The other bit of customization here is the 'Super Alt F4' which does Alt-F4, and then Enter if tapped
|
|
again SUPER_ALT_F4_TIMER miliseconds after. This lets you Alt-F4 applications, and finally quickly
|
|
double-tap it to Alt-F4+Enter to shut down the PC.
