[As I've mentioned, I'm not in favor of the
(relatively hard-coded) approach taken so far
to add a mouse-3 context menu.  I presented the
advantages of the approach taken by mouse3.el.
I've stayed out of the context-menu discussion
since then.]

I'll just mention that by default the mouse3.el
context menu when no region is active has these
menu items that are relevant here.  Enabling of
individual items depends on the type(s) of the
item detected under the mouse pointer (e.g. file,
URL, variable, function, face,...).
