We are using Codemirror to edit primarily json and I am the main developer of the internal editor where we use Codemirror. I had a request from an Linux user if we could add X window primary selection buffer functionality in the editor. I can see that in version 2.25 there was a fix for Chrome (http://codemirror.net/doc/releases.html#v2), but I cannot find the documentation of this feature. Is X window primary selection buffer functionality possible in Codemirror?
It should work in Chrome. Firefox doesn’t provide the events needed to do this, so there it doesn’t work.
Thanks 
the developer immediately switched to Chrome…
