Plasma application launchers
There are three "start menu" style Plasma application launchers in the KDE project. Kickoff which is the current default application launcher, Lancelot which will be available in KDE 4.2 and Raptor, which is still under development. In addition to this KRunner which replaces the "run command" dialogue, blurs the lines between desktop search, application launcher and command executor and provides a quick way to run applications or open documents.
