I now understand what you mean since I face a very similar issue with the alt+backarrow key in browsers. I am going to keep this report incomplete and add ayatana-design as affects to this bug report that we could get feedback from design on the issue.
** Description changed: Ctrl, Alt, and Shift have historically been used as modifier keys and I believe that by themselves, should not be bound to any specific action (currently opening the HUD) by default as this interferes with too many existing functions. + + =====A USER STORY===== + It's mostly an issue when I'm in the process of hitting Alt+Tab or Alt+` and then decide that I've changed my mind and I let go of Alt. Instead of nothing happening, the HUD appears which is not what I would expect. ** Also affects: ayatana-design Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1001120 Title: Using Alt as the default hotkey for opening the HUD is not optimal To manage notifications about this bug go to: https://bugs.launchpad.net/ayatana-design/+bug/1001120/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
