I’m assuming you mean under More Settings (when you get the web page zoom.us/profile/setting page)
Personal → Settings → Meeting → Security → Remote Control
which has the description of:
“During screen sharing, the person who is sharing can allow others to control the shared content”
and the Checkbox itself says:
“Allow remote controlling user to share clipboard”.
I am familiar with this option, it appears to be defaulted to enabled for me and all my coworkers. Regardless of the default value coworkers and myself tested this option and it has made zero difference in any copy/paste tests from the desktop client (enabled on one side, enabled on both, etc.). We have tried desktop clients for Linux to Linux, Linux to Mac, Linux to Windows, Mac to Windows, etc., and in all cases the copy/paste fails.
@briandavis Have you actually tested this with other users and found it to change your results?
My coworker has resorted to opening up a second zoom instance via web browser so he can use it strictly as a clipboard buffer. So it seems the web/chrome client can copy/paste but the desktop clients appear to not work as expected. Obviously the remote controlled session has this enabled and is allowing clipboard sharing, because it works from a web client at the same time it does not work from the desktop client.
