Hey, I'm a little puzzled here. 
 
I'm trying to make a script where, you put the mouse at a position on the screen, then you press a button, and the cursor moves left from the current position. 
 
Perhaps my explaining is a little confusing, I'll try this: 
 1 2 3 4
5 6 7 8
 
Say, I hold the cursor on "1", then press a button, and it auto moves to 2, right through to 8. Oh, and have it click on each one. 
 
I would need to get the current position, then make the mouse movement go off that? That
