Alt+Right arrow key trigger a kind of Alt + Tab

Bug Description

Pressing Alt+ "the right arrow key" will trigger the window switcher.

This is probably not intended, because:

- Other arrows don't trigger it
- This shortcut is used by other applications (eg. by Firefox to go forward)
- When it was triggered, releasing all keys does not quit the switcher (unlike Alt+Tab). You have to press Esc or Enter.

I have this problem on both Oneiric and Precise (up to date). I tried with 2 different laptops.

Reassigning to Unity, because I just realized it implements it's own Alt-tab (this bug happen only on Unity and no window switcher plugin is enable in CCSM)

I don't have this problem. Probably it's a user configuration issue. Does running unity --reset fix the issue?

I just did "unity --reset", but I still have this problem.
If I press Alt and the right arrow key, the window switcher is trigered.

I get this.

Perhaps it happens after alt-tab is used once, not sure. But I am able to reproduce.

same for me with unity default settings (unity --reset).
alt +right arrow gives me an alt + tab fonction and releasing the keys it stays in the middle of the screen until I press enter !

me too

"Critical", really?

Please don't make bugs critical unless they cause system failures.
