How to change controls to other Keyboard input

[Ondřej Ševčík]

Is it posible to change vim controls to be independent on input  
characters? I use english and czech keyboard and they have different  
key layout. Can I translate keys in command mode? I need to ů have  
same meaning as ; becouse they are on same key.  It's really hard to  
use Vim with czech keyboard, but i need to write thesis in czech of  
course.
Thanks for advices.

Best Regards.
