In my 11.04, the <Alt>Right was used to put a window to the right half side of the screen. I configured it via CompizConfig Settings Manager.
I just upgraded my system to 11.10, all other customized shortcut keys keep working, except this <Alt>Right. Now it has the same functionality as Alt+Tab, so swithing application.
I have checked CompizConfig Settings Manager, which is still as before. And the Shortcuts list of Keybord setting, it seems that no one uses <Alt>Right.
Does anyone know what happened? Thank you
