    Does anyone know if it is possible to have a tv:choose-variable-values-window
    be a command-menu (permanent) rather than a pop-up menu or a momentary menu?  
    If not, are there any ideas for ways to acheive the same behavior, namely, 
    have a menu with choose-variable-values functionality that is always exposed 
    and activated?
				    Thanks in advance, Dave

If you're working with a DW Program Framework, the way to do it is 
the :ACCEPT-VALUES-FUNCTION keyword on an :ACCEPT-VALUES pane.
