Oh, hmm.  I can see a couple of solutions.  One is to require the "pick" 
keys be different from the normal "edit" keys.  Another is just to use 
"pick" keys that the use won't miss much.

My IDE does this.  I'm pretty sure it captures the keys, and doesn't 
"pass them back up".  Things would be confusing if it did.  There's only 
four keys the pop-up menu needs.  Up and down arrows to select, enter 
key to pick the selection, and escape to dismiss the pop up.  Most folks 
won't miss those keys, or they can hit escape first if they need to use 
the arrow keys or press enter.
