multiply can be used when you're coloring with a lineart layer. the color layers on multiply mode make it so that the color doesn't go over the black lines. :X
the only keys i use in photoshop is alt+ctrl+z (undo), f (full screen), shift+ctrl+n (new layer), i (eyedropper tool), e (eraser) and b (brush). i don't really think anything else is necessary besides those. hurr
