Hi, I have a simple problem here that i cannot solve.

I want to use arrowkeys to increase or decrease the values of my variables:

xpos = 5 ; ypos = 5 ;

I want to use the up, left, right, down arrowkeys to increase or decrease the values for xpos and ypos with +1, -1. So right arrowkey => xpos = xpos + 1 down arrowkey => ypos = ypos - 1

How do I do that?

This can't be done with arrow keys, but can be done by putting the cursor on the number, right-clicking and selecting "Increment Value and Run Section"
