Thanks, Chris. I might use this for extended help, but I think that 
context-sensitive help is usually a short explanation of what a 
particular menu choice does and how to proceed, or an explanation of 
something in the text. It seems to me that the most user-friendly way to 
present this information would be with a dialog box with an OK button. 
This can be done using the SWT MessageBox class. Hsow much  is this used 
in applications? When I tried presing F1 on some MSWord menu choices it 
certainly was not what I got.

Time for more dumb questions from someone who hasn't been coding in Java 
very long. Answers from the experts will considerably speed up 

I imagine that I have to designate a listener for whatever key is used 
for help. Can I set this up for the whold GUI or do I have to do so for 
the Braille view and Daisy view individually?

Once the listener gets control, how does it determine where in the 
context it was called from?
