Computer keyboard togglekey that enables or disables all the letters from being typed in uppercase. When the caps lock key is enabled, the keyboard types "LIKE THIS" and when it is disabled, the keyboard types "like this." The picture shows an example of the keyboard LED's that indicate if keyboard togglekeys are enabled or disabled. In this example, the num lock key is currently the only enabled key, indicated by the blue LED. When caps lock is enabled the caps lock indicator will illuminate.
