[Gimp-user] Move pointer with cursor keys

[Helmut Jarausch <jarausch skynet be>]

Hi,

I couldn't find any solution for my problem.
For determining a so-called point-spread-function I have to count  
single pixels and record
the R,G,B values at these pixels (I'm using magnification 800% for  
this).
I'm using the "pointer" dialog which shows the coordinates and the  
values (R,G,B) of the pixel
at which the pointer points.
I would be extremely helpful if I could move the pointer with the arrow  
keys instead of the mouse.

Is there any means to achieve this?

Many thanks for a hint,
Helmut
