When you click on On Context in the Help menu, the Environment Manager
 provides a fast way to obtain context-sensitive help on any object you
 click on in the DECset Environment Manager window.

 Note that when you click on On Context, the arrow pointer converts to
 a question mark, indicating you are in Context-Sensitive Help mode.
 After the Help Widget is displayed for the window object you clicked on,
 the arrow pointer reappears.
