When you select an element in the AccuRev browser and click the edit button or right click and select edit, the file is opened in notepad by default for editing.
Is there a way to change the default editor in AccuRev?
You can use the environment variable AC_EDITOR_GUI to control which text editor gets invoked.
Note, when you double-click on a file from the AccuRev gui (windows users) AccuRev uses Microsoft's file association for opening the file. If you wish to change that behavior you must change Microsoft's file association for opening the file.
