Many KDE 3 users depended on Krun, a simple yet effective application used to execute commands. Executed simply by pressing “Alt-F2″, it was much easier to start applications using it, rather than navigating through a launch menu or opening a terminal window. The only catch with Krun was that you had to know the exact name of the command you intended to launch. With the advent of KDE 4, that has all changed.
Krunner operates independently of the Plasma desktop system as a standalone application. It includes a ton of features that make it useful beyond simple command launching. It has retained many of the features present in KDE 3 and greatly expanded them. We would fail to do it justice if we did not give it a top ten list.
