As I sit here in a public computer cluster, I notice a rather interesting phenomenon about this Sun Type 5c keyboard: all of the keys can "flip up." Just lift the back part of the key slightly, and it will stay in that position until you push hard enough to restore it to position 0. This works with all of the keys that do not have LEDs in them, namely Caps Lock, Compose, Scroll Lock, and Num Lock. It also does not work with the space bar.
Leaving a public workstation with over 100 keys flipped up can lead to very amusing episodes. Primarily, it just makes it very awkward to type.
