Earlier this month, Gary Vaughan mentioned QuickSilver on his blog. For those of you that don’t know, QuickSilver is a rather neat application launcher (amongst other things) for Mac OS X which allows you to simply launch an application by hitting a key combo, typing in the first few letters, and then pressing return / enter.

Consequently, i cannot remember the last time i explicitly went to my Applications folder to launch an application which wasn’t on my dock. So i guess i’m hooked.
Sadly not all of my computers run Mac OS X, so i don’t have the fortune of being able to use QuickSilver on them. Fortunately, they all run Ubuntu Linux, and you can almost guarantee some nut has made a free open source clone of your favourite app which runs on it.
After a bit of searching, i came across a KDE app called Katapult. It seems to get good write-up’s, so i decided to install it and then try it out.
$ sudo apt-get install katapult
$ katapult &
After starting it up, i got a nice icon which appeared in my system tray. Clicking on it popped up a big “Katapult” icon, which initially confused me a bit. Although after pressing a few keys on my keyboard, i realised it was the input dialog which i could type the name of the application i wanted to launch. For instance, if i typed “ter” and then pressed return / enter, it would launch the gnome terminal – neat!

After looking at the preferences dialog, it became apparent that the proper way to invoke the Katapult input diaog was by pressing “Alt + Space”. In addition, i could change which “Catalogs” (which is where the commands and so on are stored / processed) should be searched, as well as tweak them. Catalogs which were included by default were:
- Calculator Catalog (allows you to perform calculations by typing them in)
- Amarok Catalog (allows you to select songs from your Amarok library)
- Spell Catalog (allows you to spell check by typing “spell
“) - Document Catalog (allows you to open documents by typing their name)
- Bookmark Catalog (allows you to open firefox bookmarks by typing their name)
- Program Catalog (allows you to open applications by typing their name)
In any case, i am definitely going to install Katapult on any Ubuntu Linux desktop machines i administer in the future. It’s such a convenient time saver!
