What Is The Ubuntu Dash?

Ubuntu's Unity Dash is used to navigate around Ubuntu. It can be used to search for files and applications, listen to music, watch videos, view your photos and monitor your online accounts such as Google+ and Twitter.

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 
  • Applications
  • Files
  • Videos
  • Music
  • Photos

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.
