Bug ID: 40737
           Summary: Notepad open file dialog has no up directory keyboard
                    shortcut
           Product: Wine
           Version: 1.9.11
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal

Reproduced in notepad when using File->Open... dialog.

In Windows-7 alt-up is a shortcut for up directory.
I think that in WinXP it used to be backspace.
In Wine neither of these work. I think that the only way to move up a directory
is with the mouse which is quite inconvenient when opening files frequently.
