      <para>Since there are many applications that you can use in the desktop, this manual does not describe
the keyboard shortcuts that you can use to navigate all of the different applications.
However, the basic keyboard shortcuts are common to all applications. Access
keys also provide an efficient way to navigate an application from the keyboard.
An access key is identified by an underlined letter on a menu or control.
In some cases, you must press <keycap>Alt</keycap> in combination with the
access key to perform an action.</para>
