	handlesKeyboard: Return true if the receiver wishes to handle the given keyboard event
	handlesMouseOver: Do I want to receive mouseEnter: and mouseLeave: when the button is up and the hand is empty? The default response is false, except if you have added sensitivity to mouseEnter: or mouseLeave:, using the on:send:to: mechanism.
	keyStroke: Handle a keystroke event. The default response is to let my eventHandler, if any, handle it.
	mouseEnter: Handle a mouseEnter event, meaning the mouse just entered my bounds with no button pressed. The default response is to let my eventHandler, if any, handle it.

	descriptionForPartsBin If the receiver is a member of a class that would like to be represented in a parts bin, answer the name by which it should be known, and a documentation string to be provided, for example, as balloon help. When the 'nativitySelector' is sent to the 'globalReceiver', it is expected that some kind of Morph will result. The parameters used in the implementation below are for documentation purposes only!
