ShortcutRegistry class

A class used by ShortcutRegistrar that allows adding or removing shortcut bindings by descendants of the ShortcutRegistrar.

You can reach the nearest ShortcutRegistry using of and maybeOf.

The registry may be listened to (with addListener/removeListener) for change notifications when the registered shortcuts change. Change notifications take place after the current frame is drawn, so that widgets that are not descendants of the registry can listen to it (e.g. in overlays).
