AHK Script to add Middle Click MDI functionality to DOpus Light

As I understand it, if you want the same in Opus Pro you can do the following (without installing anything extra):

  1. Change Settings > File Types > All Folders > Events > Middle double-click to run:
    Go NEWTAB=findexisting.

  2. Turn on Preferences / File Displays / Mouse / Single middle click to trigger middle double-click events on background and files.
