Control iTunes without leaving what you're doing.
Control iTunes -- Whether it's to pause the player, adjust the volume, skip a track or rate a song, you can do all that and more with simple customizable keystrokes. That's not all. You can even search your iTunes Library or Playlists with a simple keystroke, all without switching to iTunes!
See what's playing -- Why bring up iTunes just to see what's playing? SizzlingKeys features a floating window that shows you the current track info. Place it anywhere you wish on the screen by simply dragging it.
Easy setup -- Having all the features you can imagine is useless if the app is difficult and confusing to use. That's why we make ease-of-use our top priority. Customizing SizzlingKeys cannot be easier.
Extras -- SizzlingKeys is more than an iTunes controller. We figure since you are going to have a hot key app running in the background anyway, why not let it handle a few more functions? SizzlingKeys lets you optionally define hot keys for system functions like Sleep and Fast User Switching.
