The Red Hat Enterprise Linux 6 GNOME desktop is initially configured with Application, Places and System menus located in the panel running across the top of the desktop area. As new software packages are added additional options will be added to the menus (typically the Applications menu though also the System menu in the case of administrative tools).

Aside from adding new software packages, the desktop menus may also be fully customized by the user in terms of adding new menu items, adding new menus, and changing the order of items in the menu. Various approaches to achieving this level of customization of the RHEL 6 GNOME desktop menus will be covered in this chapter.

== Installing the alacarte Package ==

In previous RHEL releases the package that provides the menu editing functionality outlined in this chapter was installed by default. In RHEL 6, however, this package must be installed manually prior to performing any menu configuration tasks. The package in question is called alacarte and may be installed either using the command line or the Add/Remove Software tool. To install the package from the command line, open a terminal window (''Applications -> System Tools -> Terminal'') and enter the following commands (including the root password when prompted):

<pre>
su –
yum install alacarte 
</pre>

If you prefer to use the graphical tool, select the ''System -> Administration -> Add/Remove Software'' menu option, enter alacarte into the text box and click the ''Find'' button. The search should result in Menu Editor for the GNOME desktop package appearing in the main window. If it is not already installed set the check box and click on the ''Apply'' button to initiate the installation.

Once the package has been installed it will be necessary to log out of the current desktop session and then log back in before proceeding with the remainder of this chapter.

== Customizing an RHEL 6 Desktop Menu ==

To customize a menu, right click over the menu name in the panel and select ''Edit Menus''. The Main Menu dialog will subsequently appear as follows:

The left hand panel lists the main top level menus together with the sub menus for each menu (for example ''Accessories'' is a sub menu of the ''Applications'' menu). Selecting an entry in the Menus list causes a list of items in that menu to appear in the right hand panel.

== Moving Menu Items ==

The position of existing items in a menu may be moved up or down or down to a new location simply by selecting the item in the list and pressing the ''Move Up'' and ''Move Down'' buttons respectively. 

== Adding and Deleting a Menu Item ==

A new item may be added to a menu by selecting the menu in the left hand Menus list and clicking the ''New Item'' button. This will display the Menu Item Properties dialog as illustrated in the following figure:

In the Name field, enter the name to be displayed in the menu. Next enter the path and name of the command to be launched when the menu item is selected into the Command field. If you are unsure of the full path to the tool, use the Browse option to navigate the file system to find the application executable. For example, we might want to add a menu option to launch the ''gedit'' editing tool. To do so we would enter ''GEdit'' into the Name field and ''gedit'' into the Command field. The Comment field provides a place to enter optional descriptive text which will be displayed if the mouse pointer hovers over the menu option.  If you would like to designate an icon to appear next to the text in the menu click on the button displaying an icon and navigate to the image you would like to use.

A menu item may be hidden or deleted entirely. Hide a menu item simply by turning off the toggle next to the item in the menu configuration dialog. Delete an item by right clicking it in the menu configuration dialog and selecting ''Delete'' from the popup menu.
