+### Fall-through
+When a key is undefined on a particular layer, the key
+definition on the previously stacked layer will be used. Eventually
+the key definition will be set to using the default layer. If the None

+take place.
+###Latch
+When referring to keyboards, a key function that is only enabled
+until the release of the next keypress.
+###Lock
+When referring to keyboards, a key function that is enabled until
+that key is pressed again (e.g. Caps Lock).
+### NKRO
+N-Key Rollover is the capability to press N number of keys at the

+### Scan Code

+### Shift

+that key is held.
