Double-click the file in one of the navigation views to launch the external editor.
If an editor for INI files is not registered with the underlying
operating system the Workbench will attempt to use its own default text
editor. If this happens, to see an external editor, import another file
(see previous sections) that is associated with a third party editor. Double
click again on this new file and the selected editor will open in its own
window.
The Workbench supports OLE document editors, and some editors provide OLE
document support allowing it to be opened in its own window, or embedded
inside another window like the Workbench. This will be discussed in more
detail in the next section.
