Use the launcher to start applications
The Launcher is one of the key components of the new Unity desktop. When you log in to your desktop, it will appear along the left-hand side of the screen. The launcher provides you with quick access to applications, workspaces, removable devices and the trash.
If an application that you want to start using is present in the launcher, you can click on that application's icon, and it will start up, ready for you to use.
