The external viewer command is provided as a means to launch a secondary module viewer. The external viewer application is completely user configurable. See the Configure External Module Viewer... command for more information.
If the active view is the Module Dependency Tree View, Parent Import Function List View, or Export Function List View, then this command will launch the external viewer application with the module that is currently selected in the Module Dependency Tree View. If the Module List View has the focus, then Dependency Walker will launch a separate instance of the external viewer application for every module that is selected in the list.
|Keys:||ENTER (while one or more modules are highlighted in the active view)|
|Mouse:||Double-click on a module.|
