In order to make it as easy as possible, the KDE Control Center has organized similar options into groups. Each group is called a module. When you click on the name of a module in the left window, you will be presented with the options of the module on the right.
Each module will have some or all of the following buttons:
This button will give you help specific to the current module. The button will show you a short summary help page in the left window. At the bottom of that window, you can click on a link to get more detailed help.
This button will restore this module to its default values. You must click to save the options.
Clicking this button will save all changes to KDE. If you have changed anything, clicking will cause the changes to take effect.
This button will “Reset” the module to the previous settings.
You must save the options of the current module using before you can change to a different module.
If you try to change without saving your options, you will be asked if you want to save your changes, or discard them.
