Can't Display Keyboard Shortcuts in Popups

[Ray]

Peter - many thanks for your thoughts here!  I believe the answer is to 
just manually include the "    ...ctrl+A" in the menu item.   The 
limitation with this solution is I can't 'right justify' the keyboard 
shortcut part of the menu item.  Thus, other menu items which have sub 
menus show the right pointing arrow much farther to the right.  I guess 
I could duplicate the contextual menu in a fixed menu bar but I like to 
avoid redundancy.

I'm actually popping up the contextual menu as a right-click choice on a 
data grid.  It changes depending which column in the grid you 
right-click.  Does that sound like bad interface to you?

> Usually popup menus are really contextual menus anyway, and give the user choices that are quite dependent on the control being clicked on. They can be (and I think usually are) constructed on the fly, to allow for, eg, actions specific to a field, or even to the text chunk clicked on. Whereas keyboard shortcuts (and the menu choices associated with them) are generally more global in scope. If you really need to have shortcuts listed in a popup menu, you could construct them yourself on the fly -- on mousedown; put "Audio   ctrl+A" into btn "myPopup"; popup btn "myPopup". I don't know when this would be actually useful, but then I don't know what you're trying to do here.
