There are a number of ways to start an application in Kubuntu, but for the
purposes of this quick guide, we will only focus on several of the most commonly
used methods.
First and foremost, The K Menu allows you to browse and start
applications. Clicking on The K Menu will present
you with a list of application categories under the “All
Applications” heading. Browse the application categories and
click on a highlighted application to start
it.
You will notice various icons on the Toolbar that represent the
applications they will start if you click them.
If you hover your mouse pointer over a Toolbar icon a description of the
application it launches will be displayed. You may add your own links to
applications that you use often to the Toolbar by
right-clicking on The K Menu icon and
highlighting ->-> and clicking on the application you
want to add.
Katapult: the new item launcher. Press Alt+Space to bring up Katapult then type the name of the program you want to run. Press enter to start the program when Katapult has found it.
