**Many thanks go out to mbebop and his tip for getting the Media Keys working in Snow Leopard**
Laptop media keys are excellent for quickly controlling iTunes and other media software. The Inspiron 1525 media keys worked on Leopard after installing both a kext and Butler, an application capable of converting your key presses into iTunes commands. The media keys are once again working, only now they function in Snow Leopard. Plus, the process only requires the installation of one application.
The application, GimmeSomeTune, is free and can be downloaded from the developers site. Simply install the app and then launch it. We now need to make two changes to the application’s settings before it’ll function how we want it to.
First, we need to program the actual hotkeys. Click on the Hotkeys tab and then the Player Hotkeys tab below. Set the appropriate Hotkeys for Play/Pause, Next Track, and Previous Track; you can ignore the other hotkeys such as Volume Up/Down as the volume media keys already control the system volume. Note that you can program the other hotkeys if you’d like, though doing so is not required.
Next, click on the General tab and check the “Start GimmeSomeTune with iTunes” option. This will do just as the name implies, allowing for hotkey control whenever iTunes is running. As an added bonus, GimmeSomeTune will also automatically quit when you quit iTunes.
And there you have it! You can now control iTunes from the media keys no matter what the active window is. While you’re customizing OS X, you might also want to check out HyperDock.
