Chapter�5.�The KDE Control Center

The KDE Control Center

The KDE Control Center

The KDE Control Center is the place to go to change any settings that affect the whole of your KDE environment. You can open it using the Control Center item in the K menu, or with its command-line name, kcontrol.

The settings are divided into several major categories, which each contain several pages of settings. To display a settings page, expand the major category by clicking on the + button next to it, and then click on the name of the page you want. The settings page then appears on the right, and you can change settings to your heart's content. No changes take effect until you click on the Apply button. If you decide, after making some changes, that you want to leave the settings as they were, just click on Reset .

If you need more help with a page, visit that page, then click on the Help tab. You might also want to look at the KDE Control Center Handbook, which you can open with the Help -> KDE Control Center Handbook .
