## Meaning

the wrong number of keys for the action's kind: a 2D axis takes four (up, left, down, right), a 1D axis two (negative, then positive), or alternate sets of them back to back

## Fix

pass a whole number of the kind's sets (`["A", "D", "Left", "Right"]` is two pairs), or an empty list to unbind the keyboard half
