How to launch an application:

Move your mouse pointer to the Activities corner at the top left of the screen to show the Activities overview. This is where you can find all of your applications. You can also open the overview by pressing the Super key.
There are several ways of opening an application once you’re in the Activities overview:

• Start typing the name of an application — searching begins instantly. (If this doesn’t happen, click the search bar at the top of the screen and start typing.) If you don’t know the exact name of an application, try to type an related term. Click the application’s icon to start it.
• Click the grid button at the bottom of the dash. You will see the frequently used applications if the Frequent view is enabled. If you want to run a new application, press the All button at the bottom to view all the applications. Press on the application to start it.
• You can launch an application in a new workspace by dragging its icon to the empty workspace at the bottom of the workspace switcher, or to the small gap between two workspaces.

Work with windows:

Maximize and unmaximize windows:

To maximize a window so that it takes up all of the space on your desktop:

1. Grab the window’s titlebar and drag it to the top of the screen.
2. When the screen is highlighted, release the window to maximize it.

To restore a window to its unmaximized size:

• Grab the window’s titlebar and drag it away from the edges of the screen.

Switch tasks:

1. Move your mouse pointer to the Activities corner at the top left of the screen to show the Activities Overview where you can see the currently running tasks displayed as small windows.
2. Click a window to switch to that task.
