// This exists for the purpose of being able to
// automatically coerce a string into a ButtonHandle;
// for most purposes, you should use either the static
// KeyboardButton/MouseButton getters or

//
// Each button is allowed to have one alias, and
// multiple different buttons can refer to the same
// alias. The alias should be the more general name for
// the button, for instance, shift is an alias for
// lshift, but not vice-versa.
