What kind of keyboard do you have?
Choose the model that best fits your system. If you can't find an exact keyboard match, choose the best Generic match (for example, Generic 101-key PC).
Then choose the layout type for your keyboard (for example, U.S. English).
If the language you've selected uses special characters that must be composed with multiple keystrokes, select Eliminate Dead Keys. By default, Eliminate Dead Keys is not selected. If you don't know whether you require this feature, you can leave this option unselected.
