Backlight Control Button 1.6 - Version for MessagePad 130. If you have a MessagePad 2000, please use Backlight Control Button 2. This "Newton Extension" places an invisible button behind the area of the silkscreened keys. The preferences are located in Extras, Prefs (may you have to change the folder to Setup) followed by Backlight Control Button 1.6. Once in the preferences you could drag around the grey square to set the invisible button position. Backlight Control Button works in portrait and landscape mode! The position of the invisible button will stay at the same place in both orientations. Backlight Control Button it's faster and hopefully better than allways 

messing around with the power switch!
