<!-- ==== Usage ====== -->

  <sect1 id="zenity-usage">
    <title>Usage</title>

    <para>
	When you write scripts, you can use &app; to create simple dialogs that interact graphically with the user, as follows:
    </para>
    <itemizedlist>
      <listitem>
        <para>
	    You can create a dialog to obtain information from the user. For example, you can prompt the user to select a date from a calendar dialog, or to select a file from a file selection dialog.
        </para>
      </listitem>
      <listitem>
        <para>
	    You can create a dialog to provide the user with information. For example, you can use a progress dialog to indicate the current status of an operation, or use a warning message dialog to alert the user.
        </para>
      </listitem>
    </itemizedlist>
    <para>
	When the user closes the dialog, &app; prints the text produced by the dialog to standard output.
    </para>

    <note>
      <para>
        When you write &app; commands, ensure that you place quotation marks around each argument. 
      </para>
      <para>
        For example, use: <screen><userinput><command>zenity --calendar --title="Holiday Planner"</command></userinput></screen> Do not use: <screen><userinput><command>zenity --calendar --title=Holiday Planner</command></userinput></screen>
      </para>
      <para>
	If you do not use quotation marks, you might get unexpected results.
      </para>
    </note>

    <sect2 id="zenity-usage-mnemonics">
      <title>Access Keys</title>
	<para>
	  An access key is a key that enables you to perform an action from the keyboard rather than use the mouse to choose a command from a menu or dialog. Each access key is identified by an underlined letter on a menu or dialog option.
	</para>
	<para>
          Some &app; dialogs support the use of access keys. To specify the character to use as the access key, place an underscore before that character in the text of the dialog. The following example shows how to specify the letter 'C' as the access key:
	</para>
	<screen><userinput>"_Choose a name".</userinput></screen>
