What's Lancelot ?
Lancelot is an application launcher menu (or ALI) for KDE 4 designed to provide a place from which all your jobs begin. It provides quick access to applications, places, documents, contacts and system information.

Features :

• No-click interface that allows you to navigate through the menu, and perform any action just by movingthe mouse - without making a single click (can be disabled)
• Arranging the items in the menu depending on the position of the menu button which activates it, sothat the most used categories appear nearest to the mouse
• Advanced search thanks to the integrated KRunner. So there is no need anymore for using two completelydifferent applications that have basically the same purpose, but different approaches (although I do love KRunner)
• Ability to place parts of the Lancelot menu directly onto your desktop or panel just by drag and drop.
