Version: unspecified (using KDE 4.8.0) OS: Linux Upon adding a custom Alt+Shift+<key> shortcut in "Shortcuts and Gestures" or "Window Behavior" in the System Settings, the following message is displayed: "The key you just pressed is not supported by Qt". Coincidentally, while displaying this message box, all keyboard actions are suppressed for the rest of the system. Additionally, in the System Settings > Window Behavior > Task Switcher screen, the Apply button is always greyed out, regardless of making a valid change in the settings. This behavior does not occur in the global System Settings > Shortcuts and Gestures screen. Reproducible: Always Steps to Reproduce: 1. Go to any keyboard shortcuts configuration screen, e.g. System Settings > Shortcuts and Gestures. 2. Try to set a custom shortcut containing the Alt and Shift keys. Actual Results: Immediately upon holding Alt+Shift, the unsupported key message is displayed. Expected Results: The Alt+Shift combination should be valid. I am using the US International w/dead keys keyboard layout.
I recently discovered that Alt + Shift was in use as the shortcut to change keyboard layouts, in the Input Devices settings, which triggers this error message immediately upon trying to use it in another shortcut. Changing or removing this shortcut resolved both this issue and the one in bug 294249 for me, but a clearer error message explaining the occupied shortcut would be useful. And perhaps there could be a short delay or other measure before "locking in" the new shortcut, so that e.g. Alt + Shift + Tab can be pressed without interruption by an error thrown for Alt + Shift.
I have the same problem and solved it by assigning a different key (Alt + CAPS Lock, http://publicstatic.de/gnu/linux/images/2013-12-08-kde-keyboard-settings.png) for the keyboard layout switching. Still the message Alt + Shift "is not supported by QT" is confusing (http://publicstatic.de/gnu/linux/images/2013-12-08-kde-taskswitcher-2.png). A more speaking message would be nice ("The shortcut is already assigned to another function"). > Coincidentally, while displaying this message box, all keyboard actions are suppressed for the rest of the system. Same experience - Print screen for printing the message box did not work :)
Sidenote: I experience the same behaviour as stated in this comment https://bugs.kde.org/show_bug.cgi?id=174142#c11: The original/default shortcut is "Alt+Shift+Backtab". When it is reassigned manually by pressing Alt, Shift and Tab the new shortcut is displayed as "Alt+Shift+Tab" which seems more logical since "Backtab" implies that Shift was already pressed.
