Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

If I press the Tab key, it opens a window to shutdown, log off, etc. the computer. The Z key does "undo". The number one key reloads the page. The Esc key acts like Ctrl+Alt+Del. If I try to use any of the keys, it won't work unless I press it quickly multiple times. I don't have any sticky keys enabled under System → Preferences → Assistive Technologies.

Could you please update your question with the version of Ubuntu you're using and the make/model of your computer? –  roadmr Jan 20 '12 at 0:54

Sounds like your CTRL key is stuck (CTRL+Z is normally undo). Try a different keyboard (if on a laptop, try an external one) to see if that works.

Also try cleaning your keyboard.

Thank you. I just plugged in my USB keyboard, and it worked, is there a way to get the key "unstuck?" –  Tony Son Jan 20 '12 at 0:57
    
The only way to get it unstuck is to clean it. SUCCESS!!! –  Tony Son Jan 20 '12 at 2:56
