I noticed when I was helping someone install R on their system that"
If "R" is launched from the e16 or cairo-dock applications menu, it opens in "rxvt".
Alas "rxvt" does not allow for selecting, right-click and copy/paste like "terminology" or other terminal emulators.
This is not good as it will baffle users ....... especially those that require a lot of copy/paste.
So eithere "rxvt" requires some enhancing or we remove it as default (which might cause even more mayhem).
