Getting Katapult to Reindex Your Installed Programs
If you use Katapult (which is a fantastic feature of KDE) then you may wonder how to get it to find newly installed software in Kubuntu. Simply press Alt-Space to pull up the Katapult screen and imediately press Ctrl-C to launch the config menu. Simply exit the config menu and your Katapult will reindex it’s catalog. Unless it crashes, at which time you’ll simply need to re-launch it from KMenu -> Utilities -> Katapult.
