Nudge Kursor Key Commands

Hi,

I have a question regarding the nudge cursor key command.

Firstly, I’ll explain that I use Cubase 5.5.3 and am a blind person, which may explain why I’m asking a question which some may think is rather simplistic.

I now use Control+Numpd Plus or Control+Numpad Minus which moves the cursor forward or back by 1 second.

Can I change this to move it forward or back by say 10 milliseconds?
Or, is there another key command which does that?

thanks,
Ross.
