I have a three year old Dell XPS,  2.8Ghz PC that came with a dell multimedia keyboard.  When I first got my PC, I was able to reprogram a number of the function keys (aka hot keys) to other things to customize it for my needs.  For example, the calculator key now starts "Quicken."  I now realize that I can no longer remember how I did that.  There does not seem to be any programs on my PC for performing this customization.  I want to say there used to be program in the Control Panel for that, but not now. Dell help desk was no help.  I'm not a newbie.
How do I change these function key settings?  
Thanks.
Here's my keyboard:
