Keyboard Behaviour

Some of the FUTO Keyboard's behaviour notes:

• A default number row and bottom row will be added by the keyboard if they are not explicitly defined.
• The keyboard automatically prepends $shift and appends $delete to the final Letter Row. This can be overridden by:
  • Specifying $shift and/or $delete somewhere OR
  • Specifying an explicit bottom row
