Thank you for the reply. I'm not sure I understand the instructions.
If I disable "secondary click" in the macOS Trackpad settings I can then re-enable it in BTT (Globally) to still open a contextual menu when I two-finger tap on my Mac, and can also two-finger tap on links within Safari to open them in a tab without the contextual menu being opened?
Or would I have to re-enable two-finger tapping to open a contextual menu in every app including the Finder except for Safari? Would I still be able to open contextual menus in Safari with a two-finger tap when not two-finger tapping on a link?
There was a Safari extension called Linkthing (downloadable extension) that was able to differentiate between clicking on links with a two-finger tap and clicking elsewhere within the Safari page to initiate a contextual menu. LinkThing also allowed me to hold down the control key and click on a link to bring up a contextual menu instead of opening the link in a new tab automatically. This all worked while still having secondary-click enabled in the Trackpad preferences.
I found an old copy of the extension and took a look at some of the code. Would it be possible for BTT to replicate that functionality?
Inside the extension file I found:
