Unfortunately, this application doesn't support context-sensitive\

didn't have a grab mechanism and this is needed for context-sensitive\
|

help. Instead, you can achive much the same effect by simply moving\

the mouse over the window you're curious about and pressing the\

Help or F1 keys. You can do this anytime.

This application provides only very crude help. Besides the\

Help or F1 keys.
