Right click mouse paste

Hello can anyone tell me if you can right click to paste into adding Boards Manager URLs. I can use the keyboard shortcut CTRL + V but the right click mouse does not work.
thanks

The IDE is OLD SCHOOL in many regards.
Copy paste is still one of them.

It is usually better to do the preference edits on the file itself with the IDE closed to make sure they stick properly.
There is a link in the ide to the file location.
