So here's the story:

I usually know what I am doing, so I decided to experiment with the keyboard shortcuts in System > Preferences > Keyboard shortcuts.

Unfortunately, after I decided I liked some of the defaults better, I couldn't go back to the defaults because I had no clue what they used to be. Should have written them down...

Fortunately, I figured out the solution!!! Amazing, yes?

Here are the directions:

1. Boot the Live CD

2. When you get to the desktop, go to System > Preferences > Keyboard shortcuts

3. Write down the shortcuts you want to restore (don't forget to label them so you know what they are for!).

4. Shut down the Live CD

5. Boot-up Ubuntu normally

6. Open a terminal and use this command:
It will open the Configuration Editor

7. In the Configuration Editor, navigate to
apps > gnome_settings_daemon > keybindings

8. Now find the shortcut that you wish to change back, and click the "Value" twice (double-click is too fast - click once to select, click again to edit)

9. Type in the shortcut.

10. Repeat steps 8 and 9 for all shortcuts you wish to change back.


I would think you would do something similar if you are running KDE. Feel free to post those directions as well.

Have fun, I guess.
