The standard Ubuntu installation comes with many applications. Users can also download thousands more applications from the \application{Ubuntu Software Center}. \marginnote{Ubuntu Software Center and software management will be discussed in detail at \chaplink{ch:software-management}.} 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. Simply use the \emph{Application lens} on the Dash. This lens will automatically categorize installed applications under ``Recently Used,'' ``Installed,'' or ``Apps Available for Download.'' \marginnote{If you are new to the world of Ubuntu, be sure to read the \chaplink{ch:default-applications}. It will provide you help in choosing the application(s) that suit your needs.} You can also enter a name of the application (or a part of it), in 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 \userinput{music}, and the Dash will show you the default music player and any music player you've used).

In addition to finding applications and files on your local computer using the Dash's search bar, the search criteria is also passed to to the Internet, and results pertinent to your search criteria are return in the Dash. This is a new feature in Ubuntu with the release of 12.10. If you are concerned about local search terms being sent to external resources, you can use the ``kill switch'' provided in the privacy section of the System Settings to disable all online search results. \warning{The online search results within the Dash are turned on by default during installation. If you do not want external search results, go to \menu{System Settings \then Privacy \then Search Results} and switch \emph{off} the ``include online search results'' switch.}

Under \menu{Background}, you may choose from \button{Wallpapers}, \button{Pictures Folder}, and \button{Colors and Gradients}. When \button{Wallpapers} is selected, you will see Ubuntu's default selection of backgrounds. To change the background simply click the picture you would like to use. You're not limited to this selection though. To use one of your own pictures, click the \button{+\ldots} button, and navigate to the image you would like to use, double-click the image, and the change will take effect immediately. This image will then be added to your list of available backgrounds. If you want to choose from a larger selection of desktop backgrounds, click the ``Get More Backgrounds Online'' link at the bottom of the \window{Appearance Preferences} window. This link will open your web browser, and direct you to the \url{http://art.gnome.org/backgrounds} website.
