Answer: If you press the help key the help callback of the widget with the
keyboard focus is called (not the one containing the mouse).  You can't get
the help callback of a non-keyboard-selectable widget called. To get `context
sensitive' help on these, you have to find the mouse, associate its position
with a widget and then do the help.

The X Resource, Issue 6, has an article on implementing context help in Motif
in this manner, that is, using the mouse position to indicate the widget for
which context help is desired, as well as using resources to specify the help.

The demo program lets you toggle between using the method described in the
article and XmTrackingLocate() for comparision purposes.
