Xiaoguang Wang commented on GUACAMOLE-459:
------------------------------------------
Well, in my opinion this behavior depends.
For example, most modern terminal emulators in Linux distributions, the default
Term in macOS, the iTerm2 in macOS, and XShell/SecurCRT in Windows, all their
default right-click behavior is not to paste. The only auto-paste with
right-click I can remember is PuTTY.
So for most users nowadays, their first thought of right-click is to show a
context menu, not to paste the content in clipboard.
And, if a user is using macOS with two-finger tap for right-click, the
mis-touch may cause unwanted auto-paste.
Anyway, precise behaviors are good for daily usage. It is horrible if there is
something like "rm xxx" in the clipboard and then the auto-paste behavior
triggered by mistake.
Guacamole is the best gateway I ever meet, if there is a dialog to confirm the
paste action, it would make the users (and administrators) feel easy.

> SSH auto-paste with right-click is very dangerous and may cause
> mal-operations.
> Usually the user won't know what is in his clipboard. When he right-clicks,
> the unknown commands get executed in SSH.
> I think this should be improved. eg:
> 1. add a option to disable this right-click-auto-paste feature
> 2. make a dialog to confirm the auto-paste
> 3. right click triggers a context menu
