  (Note)
   .On Linux there are 3 clipboard named PRIMARY,SECONDAY and CLIPBOARD.
    gnome-terminal use PRIMARY by Shift+Insert and use CLIPBOARD by menu selection.
    xe and gedit etc. use CLIPBOARD only.
    gnome-terminal pastes just selected range,xe pastes explicitly copyed/cut range.
    So the lines copyed on xe is pasted by menu selection on gnome-terminal not by S+Insert.
    See http://standards.freedesktop.org//clipboards-spec/clipboards-0.1.txt.
