Turn monitor off with a keyboard shortcut with AutoHotKey

monitor-off.ahk

; This is part of my AutoHotkey [1] script that turns off my monitor when I
; press Win+\.

; It also turns the screensaver on at the same time, so that Windows Live
; Messenger (and any other programs) know I am away.

; I don't have a password on my screensaver, so there is a second version
; (Win+Shift+\) that locks the PC as well.

; Note: Sometimes the monitor comes back on after a second and I have to
; press it again. Not sure why. Adding "Sleep" to pause first didn't help.
