Kicker (also referred to as KDE Panel) is the main panel used in KDE 3 and earlier, and also in the TDE desktop.

It also has the Desktop Preview & Pager, the Taskbar, the System Tray, and the Clock.

[1] The graphical shells KDE Plasma 4 and KDE Plasma 5 being widget engines of their own, SuperKaramba is no longer necessary and e.g. "Kicker" was re-implemented as such a desktop widget.

Kicker can be launched separately in other windowing environments that lack a panel of their own, such as twm, and in case the twm menu lacks some of the commands that Kicker may have.

This can be done by editing a .twmrc file, or from a terminal emulator: Kicker can embed various applets into itself.
