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:

• On the Gnome desktop go to the System menu.
• Choose Preferences and then Keyboard.
• On the Keyboard Preferences dialog, choose the Layout tab.
• Click on the Layout Options button.
• From all the available options, expand CTRL Key Position.
• Check the Swap Ctrl and CapsLock option.
• Click the Close button of the Keyboard Layout Options dialog.
• Click the Apply System-Wide button of the Keyboard Preferences dialog.
• Provide credentials if/when asked.
• Click the Close button of the Keyboard Preferences dialog.
• 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.
