In settings, you will see keyz configurator ( assuming you are using Open Zaurus -probably the same in other roms too). Select which maps will be available for your session from there.
Make sure you fill in a name for the layout you choose.
Also, be sure you did not make any mistakes in your new keymap. If you made a mistake, the program will not load, or will behave in strange ways.
You should see an entry between your \'paste\' icon and your flash card icon that says \'en.\' If you click on it, you will see a menu that includes \'en\' and watever other keymap you
added. The input from your keyboard will now reflect the layout you have picked.
