draw circles from center
I'm looking at "Create a shape on a shape layer" in the documentation for Photoshop CS6 (PDF) on how to draw a circle from the center. It states that to do this for Windows press Alt [not hold?] but when I do this the tool changes to the eye dropper or if I hold Shift and Alt the behavior is the same as if I simply hold the Shift. If I happen to be on a shape layer when I hold the Shift a "+" shows next to the cursor and if I hold the Alt as well as the Shift then an "x" replaces the "+" then if I release the Shift the symbol the "x" changes to a "-". In any case I end up drawing a circle or an ellipse and in both cases I don't draw from the center. What am I missing?
Thanks,
Chris
