I only recently learned that when using the MacOS trackpad with the terminal, you can simulate a middle button click to paste: Highlight some text anywhere in the console, drag it a little and let go. As you pull the text, a little green arrow will pop up and when you let go of the drag (anywhere) it'll paste the text into the prompt, just like middle click does.
replyMaybe everyone has known this forever and I'm the last to find out, but I thought I'd share as it was a revelation. I middle click all the time when using a mouse, so it was nice to finally discover a replacement while using the trackpad.
That's drag and drop.[1] App support is varied on this.
replyAlternatively, though I don't know if it works on Mac, on X11 Linux you can middle click with touchpads by tapping with 2 fingers. Tapping with 3 fingers right clicks. That's going to work anywhere clicking does, because it's handled by the touchpad driver rather than by app convention. If it doesn't work by default, it can be configured with `synclient`.
