copy and paste, under Wayland, and to and from an XTerm, was relating to dl audio and video

Hello Craig, Many thanks for your excellent posts, I am learning more. However I have Debian 10, nominally up to date, and it has Wayland with Gnome as the desktop. I am finding it very frustrating that I cannot copy and paste to and from the XTerm window. I used to be able to do with earlier terminal emulation under the XWindows system. I used it to be able to copy text from a terminal into an email, and commands back from email, ensuring that I did not make typos. I do understand that there can be security issues if used without a measure of care and thoughtful, but it also has much merit when coping with some of the regular expressions that come up as examples in email and on web pages. Regards, Mark Trickett
