Visual overview of GNOME
GNOME 3 features a completely reimagined user interface designed to stay out of your way, minimize distractions, and help you get things done. When you first log in, you will see an empty desktop and the top bar.
The top bar provides access to your windows and applications, your calendar and appointments, and system properties like sound, networking, and power. In the system menu in the top bar, you can change the volume or screen brightness, edit your Wi-Fi connection details, check your battery status, log out or switch users, and turn off your computer.
Activities overview
To access your windows and applications, click the Activities button, or just move your mouse pointer to the top-left hot corner. You can also press the Super key on your keyboard. You can see your windows and applications in the overview. You can also just start typing to search your applications, files, folders, and the web.
On the left of the overview, you will find the dash. The dash shows you your favorite and running applications. Click any icon in the dash to open that application; if the application is already running, it will have a small dot below its icon. Clicking its icon will bring up the most recently used window. You can also drag the icon to the overview, or onto any workspace on the right.
Right-clicking the icon displays a menu that allows you to pick any window in a running application, or to open a new window. You can also click the icon while holding down Ctrl to open a new window.
When you enter the overview, you will initially be in the windows overview. This shows you live thumbnails of all the windows on the current workspace.
Click the grid button at the bottom of the dash to display the applications overview. This shows you all the applications installed on your computer. Click any application to run it, or drag an application to the overview or onto a workspace thumbnail. You can also drag an application onto the dash to make it a favorite. Your favorite applications stay in the dash even when they’re not running, so you can access them quickly.
Clock, calendar & appointments
Click the clock on the top bar to see the current date, a month-by-month calendar, a list of your upcoming appointments and new notifications. You can also open the calendar by pressing Super+M. You can access the date and time settings and open your full calendar application directly from the menu.
Lock Screen
When you lock your screen, or it locks automatically, the lock screen is displayed. In addition to protecting your desktop while you’re away from your computer, the lock screen displays the date and time. It also shows information about your battery and network status.
Window List
GNOME features a different approach to switching windows than a permanently visible window list found in other desktop environments. This lets you focus on the task at hand without distractions.
