Synaptics Touchpad Toggle

synaptics.ahk
; Script to turn the Synaptics Touchpad on and off. Useful for laptops with
; Synaptic touchpads that do not have dedicated touchpad on/off buttons. I use
; this code to quickly toggle on and off the touchpad on my Lenovo Thinkpad,
; where I primarily use the TrackPoint.
