What Is the Command to Open the Unity Dash? To access the Dash within Unity, click on the top button on the launcher (The Ubuntu Logo) or press the super key on your keyboard (The super key is the one that looks like the Windows logo on most computers). Unity Scopes and Lenses Unity implements something called scopes and lenses. When you first open the Dash you will see a number of icons at the bottom of the screen. Clicking on each of the icons will display a new lens. The following Lenses are installed by default: Home ApplicationsFilesVideosMusicPhotos On each lens, there are things called scopes. Scopes provide the data for a lens. For instance, on the music lens, the data is retrieved via the Rhythmbox scope. On the photos lens, the data is provided by Shotwell. If you decide to uninstall Rhythmbox and decide to install another audio player such as Audacious you can install the Audacious scope to view your music in the music lens.
