[From PBarnes] PBarnes sent a software recommendation for Treo users and the software is KeyLight. "This program allows you to save batterylife on your Treo 650/680.
About the program:
# Easy to use
# Not expensive
# Allows you to set the keylight of the keyboard for different programs. Lets say you don't want the keylight to be active in the Launcher, but in the SMS-Manager.
# Many other options included, like switch off the keylight during a call, or disable the keylight after a reset
# The program also allows you to set a function that the keyboard will flash when you receive a SMS.
# Many new functions"
