US keyboard recognition problem

[WNScriven aol com]

Hello

[RedHatLinux 8] 
I changed the default 'US' keyboard to 'UK' in the installation process.
I have used "loadkeys us" and have successfully changed it so that it prints 
the correct characters (particularly | \ and ~ ) when booted up in text mode.
But when I go to Gnome and start to use a Terminal window, they are wrong.
Worse still - | is nowhere to be found, which is rather restrictive!
I have also used the installation CD and the Update function but it hasn't 
changed the Gnome corruptions to key presses.
Is there a graphics keyboard config I don't know about or should I be 
thinking about a complete re-install?

Thanks
Bill
