In Motif 1.1, almost all widgets have the translation:

	<Key>osfHelp:       Help()

Therefore, pressing the "osfHelp" key while the pointer is over the
widget will invoke its Help callback, if available.  Otherwise, it
looks at its ancestors for a Help callback.

On many systems, the "osfHelp" key is the F1 key.
