It's very lucky for me to discover shortcuts for photoshop CS3 and CS2 presented by Trevor Morris.
It's really amazing, great, and wonderful. However, we have to set them (can see how Jennifer make it..) and the most difficult part is we have to memorize them all. It's like my dull memory being insulted every time I tried to memorize and accidentally forgot them all in an instant.
But hey, why don't we set our shortcut to be windows way? We just need to quickly access to the menu bar and pull down all the menu inside, sounds nice.. Let's give it a try!
First of all, we need a very powerful keyboard shortcut to access directly to the menu bar. And for the sake of our comfort, I prefer to change it (and also recommend you)
?.
Now we can easily reach our menu bar just like those windows fellows' *ALT+F*. The difference is, the pop down menu won't reveal itself unless it's told to do so.
Thing is getting more and more interesting now. After make sure that your 
is highlighted, you can jump from one menu to another menu by typing a little portion of menu tab you want to go. I provide you example, maybe you need it (I am not insulting your intelligence, really).
Ok, I don't want to spoil you too much, experience it yourself, that's the best way to master your shortcut. Enjoy experience with your new photoshop skill.
