Cannot find the Quick Mask tool

Hi,
I seem to have a brain freeze this morning. I am looking for the Quick mask tool. In the Help file, I looked at the Quick Mask mode, but do not see any mention of the tool. Where can I find it.

Under Mask/Quick Mask Options, it shows an icon, but I do not see it on the tool box. What am I missing?

Thanks,

Lou

it's not a tool, per se, but a mode. press Q to enter quick mask, then use a brush type tool to paint with it.

It lives with the magic wand tool

that's the quick selection tool (new in cs3), not the quick mask "tool". :P
