EXPLORE THE UNITY DASH
It's a shameless steal from Jorge Castro's The Power User's Guide to Unity, which has links to all manner of useful Unity stuff over there.
One such is the link to the Ubuntu.com 'What's New' look at the Unity Dash, with a rather splendid 8-point guide to finding your way around the Dash.
“When you click on the Ubuntu logo in the top-left corner of the launcher, the new Dash will appear. It’s another simple way to get to your shortcuts and search for other applications and programs. So you can get fast access to your email, music, pictures and much more. And you can search by type of app or file with our new filters menu.”
1. Click on the Ubuntu logo to get to your apps, programs and shortcuts.
2. Look for apps and programs by typing into the search box.
3. Filter results by app or file type.
4. Access your apps, emails, pictures, music and more, fast.
5. The launcher will be disabled when you’re in the Dash.
6. Find apps by category, fast.
7. Superkey shortcut: tap the Superkey to reveal the Dash.
8. Press escape on your keyboard at any time to leave the Dash.
Life Through a Lens
It's another item of new terminology that we're going to see more often in Unity: what is a Lens?
Our faithful guide to all things Unity, Jorge Castro, provides this definition:
“It is a graphical interface for a task, it is also linked in with the dash for search results. For example when clicking the application lens it shows the apps in a nice, slick interface, with other results for like apps to download and most frequent apps.”
There's a shorter answer:
“Lenses are elements of the Unity Dash that provide a UI to search both the web and application data.”
We've shown the illustration of the Music lens on this page.
There's already a stack of third- party lenses you can install to enhance your Unity experience; check out the post on Ask Ubuntu for examples and installation instructions, but bear in mind these are third party developed and not from Canonical, so install at your own risk and expect the occasional glitch.
