To get started, try navigating the GNOME 3 desktop with your mouse:

1 Toggle activities and windows. Move your mouse cursor to the upper-left corner of the screen near the Activities button. Each time you move there, your screen changes between showing you the windows that you are actively using and a set of available Activities. (This has the same effect as pressing the Windows key.)

2 Open windows from applications bar. Click to open some applications from the Dash on the left (Firefox, File Manager, Rhythmbox, or others). Move the mouse to the upper-left corner again, and toggle between showing all active windows minimized (Overview screen) and showing them overlapping (full-sized). Figure 2.2 shows an example of the miniature windows view.

3 Open applications from Applications list. From the Overview screen, select the Application button from the bottom of the left column (the button has nine dots in a box). The view changes to a set of icons representing the applications installed on your system, as shown in Figure 2.3.FIGURE 2.2 Show all windows on the desktop minimized.FIGURE 2.3 Show the list of available applications.

4 View additional applications. From the Applications screen, you can change the view of your applications in several ways, as well as launch them in different ways:Page through. To see icons representing applications that are not onscreen, use the mouse to click dots on the right to page through applications. If you have a wheel mouse, you can use that instead to scroll the icons.Frequent. Select the Frequent button on the bottom of the screen to see often-run applications or the All button to see all applications again.Launching an application. To start the application you want, left-click its icon to open the application in the current workspace. Right-click to open a menu that lets you choose to open a New Window, add or remove the application from Favorites (so the application's icon appears on the Dash), or Show Details about the application. Figure 2.4 shows an example of the menu.FIGURE 2.4 Click the middle mouse button to display an application's selection menu.

5 Open additional applications. Start up additional applications. Notice that as you open a new application, an icon representing that application appears in the Dash bar on the left. Here are other ways to start applications:Application icon. Click any application icon to open that application.Drop Dash icons on workspace. From the Windows view, you can drag any application icon from the Dash by pressing and holding the left mouse button on it and dragging that icon to any of the miniature workspaces on the right.

6 Use multiple workspaces. Move the mouse to the upper-left corner again to show a minimized view of all windows. Notice all of the applications on the right jammed into a small representation of one workspace while an additional workspace is empty. Drag and drop a few of the windows to an empty desktop space. Figure 2.5 shows what the small workspaces look like. Notice that an additional empty workspace is created each time the last empty one is used. You can drag and drop the miniature windows to any workspace and then select the workspace to view it.FIGURE 2.5 As new desktops are used, additional ones appear on the right.

7 Use the window menu. Move the mouse to the upper-left corner of the screen to return to the active workspace (large window view). Right-click the title bar on a window to view the window menu. Try these actions from that menu:Minimize. Remove window temporarily from view.Maximize. Expand window to maximum size.Move. Change window to moving mode. Moving your mouse moves the window. Click to fix the window to a spot.Resize. Change the window to resize mode. Moving your mouse resizes the window. Click to keep the size.Workspace selections. Several selections let you use workspaces in different ways. Select Always on Top to make the current window always on top of other windows in the workspace. Select Always on Visible Workspace to always show the window on the workspace that is visible, or select Move to Workspace Up or Move to Workspace Down to move the window to the workspace above or below, respectively.

If you don't feel comfortable navigating GNOME 3 with your mouse, or if you don't have a mouse, the next section helps you navigate the desktop from the keyboard.
