In a popup window, if I type something that doesn't match anything, then is there some way to get back to the list without using the mouse? For example: Type F6 to bring up the Directories window. Type something that doesn't match, e.g. "foo". Then press backspace to remove what you typed. Now, the list of directories is back, but how, without using the mouse, do you move the cursor to them so that you can use the arrow keys?
