Thanks, Cosmin! As a temporary solution, I added a timer to close the combo box after a couple of seconds giving the user long enough to look at the list, then he can move through the list one item at a time with a foot pedal combination.
I like your first (TJvApplicationHotKey wrapper) solution and will use that to give full control back to the user on how long the drop down will stay open. Once using the foot pedal, its pretty hard to minimize or switch to another application, so that issue is minimized.
