That's a good idea. Do you have any thoughts on how to present it? Since the 
help screen works just like any other screen, which keys might be use for the 
expand and unexpand functions? We do have the option of overriding functions 
for special purposes, so if we can come up with functions that the ehlp screen 
doesn't use then we could override them. If we do that, we should try to find 
functions that all braille devices would offer else the feature wouldn't be 
usable by everyone.

By the way: There's been an improvement to the format. If a function has more 
than one binding then it looks like this:

   * go down one line:
     + Thumb3
     + RockerDown

Building the latest development code will give anyone who'd like to give things 
a try this new format.
