When you boot your computer and log in to a Unity session, you are greeted by the desktop you see in Figure 2.1. This screen is made up of many parts, each of which is described in this chapter.
To the left of the screen is a vertical bar. This is the Launcher (see Figure 2.2). Icons in the Launcher represent programs that are either running or which have been set to be included in the Launcher at all times. Click an icon to open a program. Right-click an icon for additional options, including an option to keep an item in the Launcher at all times.
