gradient selection

[david_myers2]

<p>I was reading an article by ron reeder about adding "flare" to an image -- not flare like the flare filter, but more of a diffusion effect that bleeds light into black and vice versa. He suggests opening an image, and on a mac pressing "option-apple-tilde" to make the selection. When I do this, nothing happens. What am I missing?</p>

<p>I am using OSX10, CS4 PS, and working in b&w with a grayscale image and 16 bit.</p>

<p>Thanks in advance, </p>

<p>how are your layers set up? on the top layer and have the grad tool selected before hitting the keyboard short cut?</p>

<p>if you have a flickr account, the couple CS groups are awesome.</p>
