Typing in the dark can lead to a lot of frustration. When you can't see the keys on the keyboard, even touch-typists can find it difficult to hit the right keys. The Panasonic CF 30 attempts to combat this problem by offering an optional backlit keyboard, which will illuminate your keys under low-light conditions. This option is especially useful on a rugged "ultra-portable toughbook," which is meant to be used in harsh conditions. Though the documentation for the feature is quite vague, adjusting the keyboard backlight is actually very simple, and the process should only take a minute or two.
