This project was a lot of fun to program. It good practice, and has a functional purpose. If you want to re purpose it feel free.

Here is the how to, for the program HOTKEYS and how to setup the VOL UP DOWN hotkeys.

You will also need the IRremote library.

To get your codes from your remote use the IRDemo sketch that comes with the library. Just make sure to add the 0x to the beginning of each code you get.
