front derailer, inner limit screw

if I just want to adjust the front derailer inner limit screw so that the derailer moves a mm or two away from the frame, meaning outward, to the right

does anyone know, off the top of your head:

1- which way do I turn the screw?
2- do I need to have the chain in any special place, meaning like on the small front chainring? & or the big rear chainring?
