|
|
* Numpad functions
|
|
* - Functions to implement an embedded numpad
|
|
*
|
|
* Notes
|
|
* - The numpad is toggled by shifting (without changing the overall current
|
|
* layer) the layer of the keys specified in this function to the value
|
|
* specified in the keymap
|
|
* - When the numpad is toggled, the numlock is set to on (for active) or off
|
|
* (for inactive) as well
|
|
* - All these functions cooperate, but if more than one layer mask of this
|
|
* type is used (by a different set of functions) at the same time, the
|
|
* second will override the first, and any keys covered by both will be reset
|
|
* to the overall current layer when either is released (even if the other is
|
|
* still pressed)
