To explore the Dash, click on the top-most icon on the Launcher; the icon contains the Ubuntu logo on it. After clicking the Dash icon, the desktop will be overlaid by a translucent windowwith a search bar on top as well as a grouping of recently accessed applications, files, and downloads. Ubuntu also includes results from popular web services. Thesearch bar provides dynamic results as you enter your search terms.
8. Find applications
A standard Ubuntu installation comes with many applications. Users can additionally download thousands of applications from the Ubuntu Software Center. As you collect an arsenal of awesome applications (and get a bonus point for alliteration!), it may become difficult to remember the name of a particular application; the Applications lens on the Dash can assist with this search. This lens will automatically categorize installed applications under “Recently Used,†“Installed,†or “More Suggestions.†You can also enter the name of an application (or a part of it) into the search bar in the Dash, and the names of applications matching your search criteria will appear. Even if you don’t remember the name of the application at all, type a keyword that is relevant to that application, and the Dash will find it. For example, type music, and the Dash will showyou the default music player and any music player you’ve used.

9. External search results
In addition to searching your local computer for applications and files, Dash will also search various online resources (e.g., Amazon.com). Results pertinent to your search criteria are returned to you in the Dash. If you concerned about local search terms being sent over the Internet, you can disable this feature in the Privacy section of the System Settings.
10. Browsing files on your computer
There are two ways to locate files on your computer—search for them oraccess them directly from their directory. You can search for a file usingthe Dash or the Files file manager. You can also use the Dash or Files filemanager to access commonly used directories (such as Documents, Music Downloads) as well as the most recently accessed files.
11. Your HomeDirectory
TheHome directory is used to store all of your personal files (rather than system files, such as applications).
In Ubuntu, by default, the contents of your Home directory are accessible for and can be read by other users who have an account on yourPC.
Thename of your Home directory matches your login name and is created when your user account is created. When opening your personal directory, you will see a collection of several directories, including Desktop (which contains any files that are visible on the desktop), Documents, Downloads, Music, Pictures, Public, Templates, and Videos. These directories are created automatically during the installation process. You can add more files and directories as needed.
