A simple AppleScript that toggles the ”Use all F1, F2, etc. keys as standard function keys" setting found under System Preferences > Keyboard. Displays a message to Notification Center telling you which one is active. I use this script via Alfred with an assigned keyword.
Just doubble click the ToggleFunctionKeys.alfredworkflow file and you are all set. The workflow uses the keyword "fn" by default.
Make a new AppleScript extension and Copy paste the contents of the ToggleFunctionKeys.scpt file into the extension.
Please note that you have to have ”Enable access for assistive devices” turned on for the application that runs this script.

Original AppleScript by kiodane.
Because the script invoke apple UI system based on preffered language, now it just supports English and Chinese, if you have chosen other language, please add corresponding literals to the langMapList in the applescript or the applescript in alfred workflow as the right format.
