Can I mirror / duplicate mouse events on both halves of my screen?

Solution 1:

(Knocking out a preliminary script that did the basic function was about as easy as I thought. It took only a few minutes and worked reasonably well. The problem is that there are lots of little gotchas and edge-cases where something might not work in some specific circumstance or if some other specific expectation exists. I’m still working on an enhanced version of the script that handles double-clicks and dragging, but while there’s plenty of examples and attempts, there are no solid, effective, and concise examples of handling these quite right at this time, so it’s a work in progress.)

In any case, the script below is an older version that I threw together (and cleaned up a bit for public consumption). It does what was asked (and a little more). There’s no real manual; you just run the script and it starts up in the mirroring mode. Mouse-clicks on either side of the screen are duplicated on the other (vertical) half. There are a few hotkeys that can be used to modify the script behavior:

• Alt+Shift+Q turns mirroring on and off
• Ctrl+Shift+Q turns autofire (rapid-repeat) on and off
• Ctrl+Alt+Shift+Q pauses the script so that the mouse behaves normally
• Ctrl+Alt+Shift+Win+Q exits the script

Here is a sample output of the script:

;   Hotkeys:
;       Alt+Shift+Q                     to toggle mirroring
;       Ctrl+Shift+Q                    to toggle autofire
;       Ctrl+Alt+Shift+Q            to completely pause the script (mouse behaves normally)
;       Ctrl+Alt+Shift+Win+Q    to quit
;
;       Defaults to single-click, mirrored
