Keyboard layout changing??!!

:confused: Hi everyone

Recently I need using arabic keyboard layout and by my job I need changing two key conditions by each other for correct and fast writting.
Would you please let me know is it possible to change keys configurations or not?
My OS is XP pro sp2.

I use KeyTweak to change things around:

Head over to Microsoft.com for multilanguage keyboard support.
