I'm working on full hotkey support for my laptop (ASUS F3KE-AP056 with OSD(I'll post the scripts when I'm ready).
My problem is that the Brightness keys send 00000086 codes at a time and the brightness up/down script is executed 3 times for one key press. How can i fix this? I need the script to be executed once per key press.
I need to stop the script from being executes for 1/4 second.

4) When i press the brightness up/down button the script should be executed only once.
