Adobe photoshop shortcuts

Question

I'm having issues with the shortcuts of Adobe Photoshop Cs2
I used to use the functions [ and ] to decrease/increase the brush size and also the shortcut to zoom in and zoom out, also I used the arrows on my keyboard to move things more precisely vs moving it with a mouse. I went to Edit> Keyboard shortcuts and i fixed the [ and ] shortcut (I typed the } but it typed a weird Y charcter but it still worked when I used ] ) However i cant find the shortcut for the zoom in and out which should be Ctrl + or Ctrl - and i dont know how I can make Photoshop recognize the arrows of my keyboard when i want to move things. Please help for these shortcuts really do make a difference epecially the arrows on the keyboard.
-Also the registration pop up window that displays when I start up  Photoshop doesnt go away even though I keep registering/ or clicking do not register.....it just doesn't go away which is annoying,

You must have Vista. You need to turn off UAC to get CS2 registration to stick.
(Vista's User Account Control: Type User Accounts into your Vista search bar; click user accounts in the program list to get the dialog to turn it off. If desired, you can turn UAC back on after registration.)
Did you accidentally reassign those shortcuts to something else?  Maybe, try setting them to Photoshop Default set or try Trevor Morris's set for CS2.

If that doesn't work, you might need to reset your Photoshop preference file.
