If you prefer to keep your hands on the keyboard, you can work with the GNOME 3 desktop directly from the keyboard in a number of ways, including the following:

 Windows key. Press the Windows key on the keyboard. On most PC keyboards, this is the key with the Microsoft Windows logo on it next to the Alt key. This toggles the mini-window (Overview) and active-window (current workspace) views. Many people use this key often.

 Select different views. From the Windows or Applications view, hold Ctrl+Alt+Tab to see a menu of the different views (see Figure 2.6). Still holding the Ctrl+Alt keys, press Tab again to highlight one of the following icons from the menu and release to select it:FIGURE 2.6 Press Ctrl+Alt+Tab to display additional desktop areas to select.Top Bar. Highlights the top bar. After it is selected, you can tab between items on that bar (Activities, Calendar, and the Top Bar menu).Dash. Highlights the first application in the application bar on the left. Use arrow keys to move up and down that menu, and press Enter to open the highlighted application.Windows. Selects the Windows view.Applications. Selects the Applications view.Search. Highlights the search box. Type a few letters to show only icons for applications that contain the letters you type. When you have typed enough letters to uniquely identify the application you want, press Enter to launch the application.

 Select an active window. Return to any of your workspaces (press the Windows key if you are not already on an active workspace). Press Alt+Tab to see a list of all active windows (see Figure 2.7). Continue to hold the Alt key as you press the Tab key (or right or left arrow keys) to highlight the application that you want from the list of active desktop application windows. If an application has multiple windows open, press Alt+` (back-tick, located above the Tab key) to choose among those sub-windows. Release the Alt key to select it.FIGURE 2.7 Press Alt+Tab to select which running application to go to.

 Launch a command or application. From any active workspace, you can launch a Linux command or a graphical application. Here are some examples:Applications. From the Overview screen, press Ctrl+Alt+Tab and continue to press Tab until the Applications icon is highlighted; then release Ctrl+Alt. The Applications view appears, with the first icon highlighted. Use the Tab key or arrow keys (up, down, right, and left) to highlight the application icon you want, and press Enter.Command box. If you know the name (or part of a name) of a command that you want to run, press Alt+F2 to display a command box. Type the name of the command that you want to run into the box (try gnome-calculator to open a calculator application, for example).Search box. From the Overview screen, press Ctrl+Alt+Tab and continue to press Tab until the magnifying glass (Search) icon is highlighted; then release Ctrl+Alt. In the search box now highlighted, type a few letters in an application's name or description (type scr to see what you get). Keep typing until the application you want is highlighted (in this case, Screenshot), and press Enter to launch it.Dash. From the Overview screen, press Ctrl+Alt+Tab and continue to press Tab until the star (Dash) icon is highlighted; then release Ctrl+Alt. From the Dash, move the up and down arrows to highlight an application that you want to launch and press Enter.

 Escape. When you are stuck in an action that you don't want to complete, try pressing the Esc key. For example, after pressing Alt+F2 (to enter a command), opening an icon from the top bar, or going to an overview page, pressing Esc returns you to the active window on the active desktop.

I hope you now feel comfortable navigating the GNOME 3 desktop. Next, you can try running some useful and fun desktop applications from GNOME 3.
