Can't seem to find any way of doing this so I'm posting it here as a suggestion. :)
I would really like to see an option that prevents the up/down arrow keys from being locked to a context-sensitive pop-up list. It's frustrating when I've typed the whole label/variable name and VA thinks I might want to choose a longer variation of that name, so up comes the pop-up list while I'm trying to cursor up or down to a different line, and it sticks the arrow keys to the confines of the list.
If the option is set, "cursoring" off the top or bottom of the list should remove the list and move the cursor up or down as necessary.
I love VA, but getting stuck in pop-up lists all the time drives me nuts. :P
