Yes, you can copy and paste using keyboard shortcuts:
* Windows or Linux: Ctrl + C to copy, Ctrl + V to paste
* macOS: Cmd + C to copy, Cmd + V to paste
Please note that copy-paste only works in one direction - from your own computer to the remote system. Specifically:
Works: You can copy content on your own computer and paste it into the remote system using the shortcuts above.
Does not work: You cannot copy content from the remote system and paste it back onto your own computer.
Also note that pasting with the right-click menu on the remote machine will not work. You must use the keyboard shortcuts.
