Here we are at the Unity desktop. This is the default interface used by Ubuntu.
In the upper right corner is the system tray. Clicking on the cog icon opens the panel, giving us our options.
From this panel you have several options, including shutting down the computer. You can also launch the system settings panel from here.
This is what the shutdown menu looks like. If you click the icon on the left, the system will reboot. If you click the one on the right, the system will shutdown.
Here is the system settings panel. From here you can make changes to your system. This is like Control Panel in Windows.
Also from the system tray you can check and make changes to your network settings.
One handy thing you can enable in the system settings window is online accounts. By logging into your social media accounts from this screen, you no longer have to log into every app.
Another handy feature is the language option in the system tray. You can change the language and keyboard maps here.
One feature that is unique to Ubuntu is the dock that it has on the left hand side of the screen. This is a quick launch bar. Here you can save your most used applications to launch a program you need. By clicking the top most icon on it you can launch the Dash.
From inside the Dash you can launch an application by searching for it. You can also search for particular things in the system. The default pane it launches is the home screen. Your most used applications will appear here.
By clicking the stylized A on the bottom of the Dash you can open the application screen. From here you can see the most recently used application. You can also view all installed applications, or see other applications to install.
You can also search for files and folders across your entire system.
Search for videos either on the system or online.
The Dash also lets you search music.
Also photos are searchable.
Finally, you can even search across social network messages from friends. This is handy if you need to find a piece of information a friend has sent you in the past.
Here we show you how to take advantage of a unique feature of the Unity interface, called the HUD. The HUD lets you find and use commands inside a program. Otherwise you would have to dig through menus to find them. To launch this, tap the ALT key to bring it up.
Finally, if you want to view all keyboard shortcuts for Unity you can hold down the META OR WINDOWS key. This screen will show up listing them.
