Configuring KDE Behavior

With the Personal Settings you can not only modify the appearance of objects, but also change the behavior of some components. In the following, find some examples.

Procedure 3.10. Changing the Cursor Behavior

If you want to deactivate the bouncing cursor that shows when starting an application from the graphical user interface, proceed as follows:

Open the Personal Settings and select Appearance & Themes+Launch Feedback.
From the drop-down list, select another option for Busy Cursor.
Click OK to apply the changes and close the configuration dialog.

You can set a number of mouse options in the Personal Settings, from cursor themes to acceleration and double-click intervals. You can also change the default Linux behavior (use single mouse-click to open files or folders) to a double-click option (like in Microsoft Windows).

Procedure 3.11. Adjusting the Mouse Settings

Open the Personal Settings and click Peripherals+Mouse.
To switch to double-clicks to open files and folders, select the corresponding option on the General tab.
To change the mouse pointer appearance, switch to the Cursor Theme tab and select a different cursor theme.
To change the default values of double-click intervals or the distance that the pointer moves over the screen on movement of the mouse, adjust the settings on the Advanced tab.
Click OK to apply the changes and close the configuration dialog.

KDE comes with a set of predefined keyboard shortcuts. You can easily create more keyboard shortcuts or change existing shortcuts, especially if they should conflict with other application-specific shortcuts. KDE also allows you to store more than one scheme of shortcuts.

Procedure 3.12. Modifying KDE Keyboard Shortcuts

Open the Personal Settings and click Regional & Accessibility+Keyboard Shortcuts.
To switch from the default scheme to a Windows or Mac based scheme, for example, click Current Scheme and select a different scheme.
Browse through the list of non-application-specific KDE shortcuts on the Global Shortcuts tab. To filter for certain keywords, enter a search string in the search field above.
For shortcuts for switching between different desktops or windows see the Shortcut Sequences tab.
To view or change application-specific shorts, select the Application Shortcuts tab.
To change or add a shortcut, select an action in the list and click Custom. A new dialog opens.
To enter a shortcut, just press the desired key or key combination. If this shortcut cannot be accepted or in case of conflict with another existing shortcut, a notification shows. If your input was successful, the new or modified shortcut appears in the list.
To save the altered settings, click Apply. To reset all shortcuts to the default values, click Defaults then Apply.

When you click a link to a Web page, KDE opens the Konqueror Web browser by default, when you click an e-mail address, KMail starts.

Procedure 3.13. Changing the Default Web or E-Mail Application

To change this behavior and set your preferred Web browser or e-mail client as default, open the Personal Settings and click KDE Components+Component Chooser.
To change the Web browser:
1. In the list of components, select Web browser.
2. Select Open http and https URLs in the following browser and click the browse button beneath.
3. A dialog opens, showing the main menu structure. Select the Web browser to set as default and click OK. The component chooser now shows the selected application in the display field.
To change the e-mail client:
1. In the list of components, select Email Client.
2. Select Use a different email client and click the browse button.
3. A dialog showing the main menu structure opens. Select the e-mail client to set as default and click OK. The component chooser now shows the selected application in the display field.
If desired, change other default applications for KDE, like the application for the terminal window or the instant messenger client.
When all options are set according to your wishes, click Apply.

Similar to setting the default Web browser or e-mail application, you can change file associations in KDE. File associations determine which application should be used to open a file, for example, if you want to start a file from Konqueror.

Open the Personal Settings and click KDE Components+File Associations.
To search for an extension, enter the extension in Find Filename Pattern. Only file types with a matching file pattern appear in the list. For example, to modify the application for *.png files, enter png in Find Filename Pattern.
In the Known Types list, click the file type to open the setting dialog for this file type. You can change the icon, the filename patterns, description, and the order of the applications.
If your tool is not listed, click Add in Application Preference Order then enter the command.
To change the order of the list entries, click the program to move then give it a higher or lower priority by clicking Move Up or Move Down. The application listed at the top is used by default when you click a file of this type.
If you need a file type that is not listed in the Known Types list, click Add to open a dialog where you can select a group and enter a type name. The group determines the main type, for example, audio, image, text, or video. Your file type can usually be assigned to one of these.
1. Click OK then determine the extensions of the filename.
2. Specify a description in the text field and select which application to use.
When all options are set according to your wishes, click Apply.
