I think I may have not replied to correct way!
The issue is not caused from using command+c and command+v. I have tried to use control+c and control+v. Whenever I do this a “^C” and “^V” displays on my terminal instead. I checked the forum that you sent which states there is a “modifier keys” button that the user can click to change keyboard input, however, this button does not exist under “keyboard and mouse” for me. Again, my “grab the keyboard input” is on. I have also tried using alt+c and alt+v which does not help either.
