Thank you for your reply. But it does not work. I’ve alraedy looked this link before. I use ctrl(left)+shift(left)+v to paste in terminal, and I also tried ctrl(right)+shift(right)+v or ctrl(left)+shift(right)+v or ctrl(right)+shift(left)+v, none of them works.
Changing focus as the link https://kb.nomachine.com/TR03V11107 said does not work either.
However, shift+insert works fine in terminal. So, I think the workaround may be using shift+insert to paste.
