Tim,

The code $05 $20 (at least when used with Display 5 20) just changes the window 
from which the code was sent. Your code sends the sequence to path #1 stdout 
which may or may not be the way to do what you want. You may need to open a path 
to a specific window and then send the code sequence to that path.

I can't remember just how this should be done for a specific window instead of 
system wide, and will have to look at some source code to jog my memory.
