Keyboard handler is triggered multiple times.

[svdsande]

Due to the fact that both key and code are checked when determining if a key is triggered, a keyboard handler could be called multiple times.

The following function will be called twice when pressing NumpadEnter

@onKey('Enter')
@onKey('NumpadEnter')
onEnterOrNumpadEnterDown(e) {
  this.args.onTrigger(e);
}

The reason for this behavior is the fact that in this scenario event.code is equal to NumpadEnter but event.key is equal to Enter Therefore when iterating over all keyboard handlers @onKey('Enter') will also be called since event.key will match. I found an older pull request #135 in which the option is discussed the specify a mode, this would enable developers to explicitly specify state if the they want to match based on key or code. Having this option would solve the problem at hand, but I understand that this proposal didn't make it in the final API design. But would it be possible to combine @onKey('Enter') and @onKey('NumpadEnter')? Let me know if I could help in any way.
