Change line weight shortcut

anybody have an answer yet?

the shortcut for the line tool - size/weight in photoshop when the line tool is set to "pixels" is assigned to "[" and "]" and if I'm not mistaken it used to be connected to the brush size shortcut.

my brush size shortcuts have been changed to "Q" and "W" and I'd like the same for the line tool but it doesn't seem there's a way to change this anywhere in keyboard shortcuts?
