I am looking for a program for Windows that can modify the behavior of a double-click so that each double-click is followed by a Ctrl + C.
This answer provides a great AHK script, but it doesn't work for me for double-clicks, because apparently AHK doesn't recognize double-clicks sent programmatically, i.e. not for the mouse but through some other software emulating mouse clicks (in my case SmartNAV + Point-N-Click Virtual Mouse).
