Open a map in a DITA map editor
This procedure lets you open a map in one of the associated map editors.
The DITA Map Editor is supplied with IXIA CCMS Desktop. The other choices that appear depend on your system configuration.
You can have several different maps open in different kinds of map editors at the same time. You can switch from one map to another by clicking the tab with the map title; your file will appear in the editor with which you opened it.
In fact, it is recommended that you have more than one style of
                editor associated with your documents. One, like the DITA Map Editor for an overall
                structural view; another, such as Simple XML Editor or Oxygen, for looking at XML details.
Note: The Open With menu option becomes available when you
                    have two editors associated with a given file extension. To get access to the
                    DITA Map Editor, simply configure Simple XML Editor as one of your *.ditamap
                    editors.
            To open a map in a DITA Map Editor:
                Right-click the map and select Open With, then select the editor from the menu list.
