kdelogoKRunner is one of those KDE applications that people generally take for granted. Since it has the same shortcut key, Alt+F2, as Gnome's Run Application terminal, those who have just started using KDE generally assume that it is just another version of Gnome's Run Application terminal. However, it cannot be farther from the truth. In reality KRunner is one of KDE 4.3's most useful application.

If you have been reading my previous articles, you would have known that KDE can be used as a very efficient application launcher. You are also probably aware that KRunner can also run BASH commands. In this article, we present 7 features of KRunner in KDE 4.3 that many people are not aware of.

1. Google  Search

To bring up Google Search results using KRunner, type gg: <some term>. For example, to search for firefox, type gg: firefox and enter. The search result will be brought up in the default web browser.
