 Further documentation on behaviors and bindings is forthcoming, but a summary of the current behaviors you can bind to key positions is as follows:
 
 - `kp` is the "key press" behavior, and takes a single binding argument of the key code from the 'keyboard/keypad" HID usage table.
-- `mo` is the "momentary layer" behaviour, and takes a single binding argument of the numeric ID of the layer to momentarily enable when that key is held.
+- `mo` is the "momentary layer" behavior, and takes a single binding argument of the numeric ID of the layer to momentarily enable when that key is held.
 - `trans` is the "transparent" behavior, useful to be place in higher layers above `mo` bindings to be sure the key release is handled by the lower layer. No binding arguments are required.
 - `mt` is the "mod-tap" behavior, and takes two binding arguments, the modifier to use if held, and the keycode to send if tapped.
