A collection of Alfred workflows I've created as well as some from people around the web.
###Generate Guid Does just what it says on the tin. You can either use a keyword of "guid" which will simply copy a new guid to your clipboard or you can hit the hotkey Cmd+Shift+G and it will copy it to your clipboard and insert it wherever your cursor currently is.
Note: This workflow requires the uuidgen application. I believe it's installed on OS X by default, let me know if that's not the case though.
###Bluetooth Toggle This one is fairly obvious. You can essentially use a keyword of "bt" or Cmd+Shift+B and it will toggle your bluetooth radio.
Note: This workflow requires the use of the blueutil application, which can be found here.
