I am an German software developer currently working privately with Unity3D. At this moment I really don't want to involve myself into the community, i really just want to update the outdated information on the following paragraph. http://wiki.unity3d.com/index.php?title=Using_Notepad_Plus_Plus_as_a_script_editor#How_to_make_Notepad.2B.2B_jump_to_the_correct_line_number_from_the_error_console If you are willing to do it yourself, you are welcome to. The information on said paragraph is no longer valid. As of right now, you can simply select notepad++ as the editor to use and manipulate the external editor args to "$(File)" -n$(Line) Nothing else needed.
