why is the copy option gone when you right click mouse

I am replying to form submission and want to copy info into the submission but the copy option when you right click is no longer an option. I just want to insert copied text. It now allows you to copy links and images, but took copy text function away when you right click????? 

To clarify, when trying to forward a submission in the submission page, you would like to insert form fields?

Can you please explain further what kind of copy option would you like to add when replying in the submission?

Looking forward for your response.
