This chapter introduces the GNOME desktop in Fedora. The desktop becomes easier to use after you know some of the common terminology used, beginning with the GNOME desktop.

To access the calendar, click the clock on the right hand side of the panel. When you double-click a date, the Evolution personal information manager opens.
Fast User Switching
If you click the current username located next to the clock, a list of available users appears. To switch to a different user account, select the username.
The volume control allows you to quickly change the overall volume of sound on your computer. Click the icon to show a slider, and then use the mouse to drag the slider to the desired volume. If you double-click the icon, a volume control window appears in which you can separately change the volume of different sound sources.
The Desktop Area
The default desktop area, or workspace, contains three icons;
- Computer - If you double-click this icon, a window appears that contains available storage devices on the computer. These are also listed in the Places > Computer menu.
- The Home icon represents the location where all of the logged in user's files, such as music, movies, and documents, are stored by default. There is a different home directory for each user, and users cannot access each others home directories by default.
- Trash does not permanantley delete your files. The disk space used in the Trash is not recovered until it is emptied. To empty the Trash, right-click the icon and select Empty Trash.
The Fedora Live CD desktop also includes an icon for installing Fedora to your hard disk. Additional icons may appear depending on your system. For example, inserting a USB stick will cause an icon to appear for accessing the stick.
Using The Desktop
Right-click on the desktop area for a menu of actions related to the desktop area. For example, the Change Desktop Background action lets you choose a different image or photograph to display on the Desktop. Add program icons to your Desktop by a left click on the program's icon and select > Add this launcher to desktop or Add this launcher to the panel.
The Bottom Window List Panel
This panel has four components:
- The Show Desktop, button, on the left side, is used to hide all open windows, and reveal the desktop area. This function is useful when the open applications obscure an important desktop file or icon. To restore the windows, click the Show Desktop button again and all windows return to their previous location.
- Any open applications appear as button icons in the middle part of the the Bottom Window List Panel. It shows all application windows in use on the desktop workspace, whether they are visible or hidden. A hidden window button appears with a white background. The currently selected application window button has a gray background, and is said to have focus. Usually, this is the application whose window is on top of all the others on the screen. To switch from one running application to another using the mouse, click on the desired application's button in the panel.
- The Workspace Switcher is the group of squares situated on the far right. They allow you to move between workspaces. Workspaces have long been a feature of UNIX and Linux desktop environments. Each workspace provides a separate desktop where applications can be organized, and a corresponding window list panel. By default there are four workspaces available. To change this number, right-click on the workspace switcher and choose preferences.
- The Trash icon on the right end of the window list panel works the same way as the Trash icon in the desktop area. If you delete a file, it is moved to this location. A right click on the Trash icon brings up the options to, Open the folder, Empty Trash, Remove from Pane, and Lock to Panel.
