I’ve found this with Windows as well, when the Scripting Terminal in Renoise will not Paste anything copied from anywhere else! I have reported it before also. Seems to come and go at random though, rather than being consistent…
EDIT: Re-reading and think that’s actually different to what you describe. Sorry. Yours sounds more a request to get what you consider OS default modes of operation working within Renoise??
Yep. In X11/unix systems like linux, middle-clicking in a text input area pastes whatever is selected in another text area, without the need to copy/paste to/from the clipboard, which has its own separate content (of mostly any type, not just text)
This is very very handy, and apps that don’t honor this are kind of annoying
