eyeball. step 6. confused!

Under the "Techniques: Creating Eyeballs? "step 6" I really dont undarstad what its saying";
Now Create a new layer directly above the eye_top layer and name this layer Highlight1. Go back to your eye_top layer and Ctrl+Click to select it. While holding down your "Alt" key we are going to minus part of the selection. Minus the selection so you only have a small wedge left in the upper right corner. You create this wedge by holding down the "Alt" key and selecting every part of the eye "but" the part you want left. Thus, the minus. But you already knew that =). Once the wedge is created switch to your Highlight1 layer and fill it with white.

The minus part of the selection part I cant figure out. I dont even know how to do it, move what, how?

please respond fast I am dying here hehe.:D

You create this wedge by holding down the "Alt" key and selecting every part of the eye "but" the part you want left.

You simply use a "selection" tool, be it... the rectangle marquee or the elipticle marquee or whatever... you do just what that quote says.. hold "alt" and drag the "subtract from the selection.

thanx chris, i already figured mine out! hehe the eye worked up fine.
