Something along this line is realised in xtex Version 2.17.1. Here are the
first few lines xtex.sty:

%%
%%      XTeX buttons for bibliography citations and references. Simply include
%%      this in your document style like..
%%
%%      \documentstyle[acm,xtex]{article}
%%
%%      and run latex once or twice. You'll notice boxes appearing around
%%      all your \ref's and \cite's. These will invoke xtex specials such
%%      that you can move around. See xtex documentation for more details.
