British and American keyboards

I think it might be the easiest to simply remap a key.

For remapping certain keys you need two tools. First xev (commandline-tool) and second xmodmap (also commandline-tool). Both should be available in ubuntu without extra installing them.

1. Start terminal window and run xev. Now it's active and waits for you to press a key. Then press the key whose behaviour you want to change. i.e. PgUp.

2. xev will output some information about the pressed key. The third line is important. It should look similar to:

   state 0x10, keycode 110 (keysym 0xff55, Prior), same_screen YES,
   

   In this example Prior is the name of the behaviour the key is assigned to at the moment, the number keycode is the internal id to recognize the key. Now do this with another key i.e. PgDown give this output

   state 0x10, keycode 115 (keysym 0xff56, Next), same_screen YES,
   

   Here again the interesting part for us is keycode 115 and Next - the name of the behaviour.

3. now when you want to swap the two keys use xmodmap.

    xmodmap -e "keycode 110 = Next"
   

   This changes the key with keycode 110 on your keyboard to the action Next. It's pretty simple.

   Note that if the key you are mapping should have a different meaning when used with the shift key (for example for British keyboard layouts, Shift+2 gives quotation marks) then you can simply list the secondary command after the first. For example if you want the key with code 53 to map to backslash normally, but to the bar symbol when used with shift, you might do:

    xmodmap -e "keycode 53 = backslash bar"
   

Note: These change are for the active x session only and will be lost after reboot. When you want to save the changes permanently you have to run the following commands after the ones above:

xmodmap -pke >~/.Xmodmap

(This creates a files called .Xmodmap in your home directory.)

Then you have to create a file called .xinitrc in your home directory where you put this commandline xmodmap .Xmodmap in.

Go to Keyboard layouts under system settings, and click on it. Once open remove English (US), and add the English (UK) that you want. Click on the Plus (+) sign to add, and the minus(-) sign to remove. See images below.

(It will be English UK with Extended Win Keys)

Hi,

The key does nothing when I press it with the UK language selected. I have to select US and use shift and “ key to make the symbol. Even the on-screen keyboard doesn’t do anything when UK is selected and I press the @ symbol.
