I can confirm that quickly pressing Alt+ left arrow will both cause firefox to go back one page and then cause the HUD to appear.
In fact, as far as I can tell, the *only* reason that this doesn't happen every single time is that if you hold down Alt too long, it times out and shows the global menu instead of activating the HUD. So basically, pressing or not pressing the arrow key makes no difference, the only thing that matters is how long you hold down Alt. Of course, this isn't the case with most other keys. For example, Alt + Home doesn't seem show this problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/969039 Title: HUD appears when tapping Alt+Left very quickly To manage notifications about this bug go to: https://bugs.launchpad.net/compiz-core/+bug/969039/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
