Having trouble with tools

Hi

I’m having trouble using tool shortcuts. Pressing any shortcut keys don’t do nothing.

They are all grayed out shown in the pic attached.

Any suggestions?

OSX10.8.5 AE CS6

 

 

I can’t see the attached pic, it isn’t loading for some reason. Can you email me the image? maryp@imagineersystems.com

 

Cheers,
Mary
