Hi - not sure if this has been discussed before, if it has, apologies, I didn't see it.

Well ... this is actually probably the most common question asked, and I have no doubt it will be asked again, but no worries. Hopefully this issue will be easy to find, and failing that easy to point people at in the future.

IMHO, pressing ctrl+alt+shift to open the left side 'clipboard' panel, pasting text, closing the panel, and then right click (to copy the content into the ssh session) is very cumbersome.

To be clear:

The reason it's done this way is because that's the only way it's possible. Browsers do not provide unrestricted access to the clipboard for security reasons. Believe me when I say that we would have implemented it the direct route in the first place if it were possible.

Guacamole does attempt to access the clipboard directly using the W3C Clipboard API, but those attempts will silently fail in almost all cases. Unless browsers decide to provide a permission granting interface for clipboard access (like what is done for microphone, camera, etc.), the only way to access clipboard directly is via an extension. There is an extension for Chrome which does this:

See:

* https://sourceforge.net/p/guacamole/discussion/1110834/thread/50098c28/ ("... Web browsers do not provide direct access to clipboard data for security reasons. ...")

* https://glyptodon.org/jira/browse/GUAC-1480 (The original issue which added support for the clipboard API, even though it's denied in most cases, and implemented the extension previously mentioned.)

> Could guacamole be enhanced to either:
> 1. allow the mouse pointer to open/close the panel
> 2. allow the user to copy and/or paste content directly onto the ssh terminal
> Thanks.
