Type Alias LabelOptions

Filters the auto labeling.

If the filter returns true, the key is not labeled.

You can also use this to label the key yourself.

Common filter actions:

• Capitalize all single character keys to match what they look like on real keyboard.
• Prevent keys with multi-line labels (e.g. Num\nLock, Scroll\nLock from getting changed).

Note the event is not always a real event because if it's the navigator labeling the key or you're using the Emulator class, there isn't a real event.

See labelWithKeyboardMap. This is required for label strategies that use the navigator. You can get the map using navigator.keyboard.getLayoutMap().
