I've placed a patch on SourceForge that moves more toward conventional X11 "selection" options, i.e., paste to clipboard than can be had using CNTRL-V in other apps as well as the variety of "selection" where the center mouse button will copy into another app.  The copy to clipboard is a static pixel map, i.e., even if you replot in that window the clipboard will remain as before until one types 'c' again.

So the variations are

<double click> - "select" mouse coords
't' - "clipboard" some sample text
's' - "select" the pixel map
'c' - "clipboard" the pixel map.

This is *proof of concept*.  Bindings can all be redone.  Behavior can be used to force something automatically on plot or splot.

One thing to consider is removing the "export_selection" variable option.  That seems like unnecessary twiddling if we get a good set of selection options.  (Unless that option is meant to be "automatic paste" or something, I don't know.)
