Whisker Menu is an alternate application launcher for Xfce.
When you open it you are shown a list of applications you have
marked as favorites. You can browse through all of your installed
applications by clicking on the category buttons on the side.
Top level categories make browsing fast, and simple to switch
between. Additionally, Whisker Menu keeps a list of the last
ten applications that you’ve launched from it.
Favorites are easy to add and reorder. When browsing through
your applications, right-click on any of them and select “Add
to Favorites”. Simply drag and drop your favorites list to
arrange them to suit your needs. You can remove them at any
time from another right-click option.
If you’re not sure exactly where a program is listed, instead
of browsing through each category you can simply enter a search
term. The search field is focused when opening the menu, so you
can just start typing. Application descriptions as well as names
are searched, which allows you to find a program by using a
general word (such as “browser” to find all web browsers
installed on your computer).
