Swap CTRL with CAPS LOCK in Ubuntu 9.04

To swap the function of the left control key with the capslock key in Ubuntu 9.04, follow these steps:

1. On the Gnome desktop go to the System menu.
2. Choose Preferences and then Keyboard.
3. On the Keyboard Preferences dialog, choose the Layout tab.
4. Click on the Layout Options button.
5. From all the available options, expand CTRL Key Position.
6. Check the Swap Ctrl and CapsLock option.
7. Click the Close button of the Keyboard Layout Options dialog.
8. Click the Apply System-Wide button of the Keyboard Preferences dialog.
9. Provide credentials if/when asked.
10. Click the Close button of the Keyboard Preferences dialog.
11. You are done.

This seems to work fine on the everything running on the Gnome desktop, including the Terminal. However, this technique seems to leave your xorg.conf file alone.
