Comment 16 for bug 348848

This has all the makings of a bug. A certain behaviour is implied to the user but fails to be provided. Either remove it from the shortcuts menu or make it work. It worked in 8.10, but has been uneven ever since. Rarely I can get the shortcuts to work, but they are not always responsive. This is especially true when moving Firefox windows where addons seem to compete with Ubuntu for key grabs.
