The installation program allows users to configure a keyboard layout for their systems. To configure a different keyboard layout after installation, use the Keyboard Configuration Tool.
To start the Keyboard Configuration Tool, select the Main Menu button (on the panel) => System Settings => Keyboard, or type the command redhat-config-keyboard at a shell prompt.
Select a keyboard layout from the list (for example, U.S. English) and click OK. For changes to take effect, you should log out of your graphical desktop session and log back in.
