Toggle AirPort.scpt is a simple AppleScript file that will either enable or disable your AirPort connection. It is best used with a program that lets you assign global hotkeys for running scripts, like Quicksilver, so you can toggle your wireless connection with a simple keystroke.
Copy Toggle AirPort.scpt to your computer.
Run the script. It's that easy.
If you are using Quicksilver, place it in a directory that is indexed. Set up a new trigger to run the script.
If Growl is installed, you'll get a popup notification.
Because OS X 10.7 (Lion) renamed "Airport" to "Wi-Fi", the original version of Toggle Airport.scpt doesn't work. Version 2, released on July 25, 2011, does though, and is completely compatible with Lion. Version 1 is still available at Github for OS X 10.6 (Snow Leopard) users.
Version 2.1 works with the new Growl 1.3, available on the Mac App Store.
