On older computers, basic system information was indicated using physical LEDs. These LEDs are often missing on modern computers or located where they are not easily visible. addLEDs displays this information directly on your screen.

addLEDs uses icons to display the status of the Caps Lock, Num Lock, and Scroll Lock keys. Each status is represented by an icon ("virtual LED") indicating the current state.
The displayed icons can also be used to toggle the corresponding key status. This feature functions as a virtual push button.
