This chapter describes how to use the preference tools to customize the GNOME Desktop.

A preference tool is a small application that allows you to change settings in the GNOME Desktop. Each preference tool covers a particular aspect of your computer. For example, with the Mouse preference tool you can set your mouse to left-handed or right-handed use, or change the speed of the pointer on the screen. With the Windows preference tool you can set behaviour common to all windows such as the way in which you select them with the mouse.

To open a preference tool, choose System Preferences in the top panel. Choose the tool that you require from the submenu.

With a few exceptions, the changes you make to settings in a preference tool take effect immediately, without needing to close the preference tool. You can keep the preference tool window open while you try the changes, and make further changes if you wish.

Some applications or system components may add their own preference tools to the menu.

Some settings for your system require administrator access. These are in the System Administration submenu.

The CD Database preference tool enables you to configure a CD database that your system can query. A CD database contains information about CDs, such as the name of the artist, the title, and the track list. When an application plays a CD, the application can query the CD database about the CD, then display the information.

Not all applications that use audio CDs use the settings in this preference tool. Some may have supply their own settings in their preference dialog.

- Best shapes: Antialiases fonts where possible. Use this option for standard Cathode Ray Tube (CRT) monitors.

- Best contrast: Adjusts fonts to give the sharpest possible contrast, and also antialiases fonts, so that characters have smooth edges. This option might enhance the accessibility of the GNOME Desktop to users with visual impairments.

- Subpixel smoothing (LCDs): Uses techniques that exploit the shape of individual Liquid Crystal Display (LCD) pixels to render fonts smoothly. Use this option for LCD or flat-screen displays.

### Inställningar för tangentbordslayouter

Use the Layouts tabbed section to set your keyboard's language, and also the make and model of keyboard you are using.

This will allow GNOME to make use of special media keys on your keyboard, and to show the correct characters for your keyboard's language.

Tangentbordsmodell

  Use the browse button (labelled with an ellipsis, ...) to choose another keyboard make and model.

Selected Layouts

  You can switch between selected layouts to change the characters your keyboard produces when you type. To add a layout, click Add. You can have up to four layouts. To remove a layout, select it and press Remove.

  To switch between keyboard layouts, use the Keyboard Indicator panel applet.

Separate group for each window

  When this option is selected, each window has its own keyboard layout. Changing to a different layout will only affect the current window.

  This allows you to to type with a Russian keyboard layout in a word processor, then switch to your web browser and type with an English keyboard layout, for example.

Click Reset to Defaults to restore all keyboard layout settings to their initial state for your system and locale.

### Alternativ för tangentbordslayouter

The Layout Options tabbed section has options for the behaviour of keyboard modifier keys and certain shortcut options.

Expand each group label to show the available options. A label in boldface indicates that the options in the group have been changed from the default setting.

The options shown in this tabbed section depend on the X windowing system you are using. Not all the following options might be listed on your system, and not all the options shown might work on your system.

Adding the EuroSign to certain keys

  Use these options to add the Euro currency symbol to a key as a third-level character. To access this symbol, you must assign a third level chooser.

Alt/Win key behavior

  This group of options allows you to assign the behaviour of Unix modifier keys Super, Meta, and Hyper to the Alt and Windows keys on your keyboard.

CapsLock key behavior

  This group has several options for the Caps Lock key.

Compose key position

  The Compose key allows you to combine two keypresses to make a single character. This is used to create an accented character that might not be on your keyboard layout. For example, press the Compose key, then ', then e to obtain e-acute character.

Control key position

  Use this group of options to set the location of the Ctrl key to match the layout on older keyboards.

Group Shift/Lock behavior

  Select keys or key combinations to switch your keyboard layout when pressed.

Miscellaneous compatibility options
  Shift with numpad keys works as in MS Windows.

    With this option selected, using Shift with keys on the numerical pad when NumLock is off extends the current selection.

    With this option unselected, use Shift with keys on the numerical pad to obtain the reverse of the current behaviour for that key. For example, when NumLock is off, the 8 key acts as an up-arrow. Press Shift8 to type an '8'.

  Special keys (Ctrl+Alt+<key>) handled in a server.

    Select this option to have certain keyboard shortcuts passed to the X windowing system instead of being handled by GNOME.

Third level choosers

  A third level key allows you to obtain a third character from a key, in the same way that pressing Shift with a key produces a different character to pressing the key alone.

  Use this group to select a key you want to act as a third level modifier key.

  Pressing the third-level key and Shift produces a fourth character from a key.

  The third and fourth level characters for your keyboard layout are shown in the Keyboard Indicator Layout View Window.

Use keyboard LED to show alternative group.

  Use this option to specify that one of the light indicators on your keyboard should indicate when an alternative keyboard layout is in use.

  The selected keyboard light will no longer indicate its standard function. For example, the Caps Lock light will not react to the Caps Lock key.

### Typing Break Preferences

Configure the Typing Break Preferences to make GNOME remind you to rest after you have been using the keyboard and mouse for a long time. During a Typing Break, the screen will be locked.

  There is no way to restore the original, default keyboard shortcut for a comamnd.

  This feature does not maintain shortcuts that are normally common to all applications, such as CtrlC for Copy. This may lead to inconsistencies in your GNOME applications.

Detachable toolbars

  Selecting this option allows you to move toolbars from application windows to any location on the screen. A handle is displayed on the left side of the toolbars in your applications. To move a toolbar, click-and-hold on the handle, then drag the toolbar to the new location.
