Thanks for the hints.  They definitely pointed me to the right places.=20
It appears to boil down to something like this:

this.GdkWindow.GetPointer(out xloc,out yloc,out mask);
TextIter ti =3D this.GetIterAtLocation(xloc,yloc);

Its *close* but only appears to be off by compound tools featured in the
editor.  If I figure out the reason for the X offset (the Y/line is
right) then all I need to do to capture the word under the pointer is
move forward to the next whitespace.  This is what I needed and
hopefully I can solve this last stumbling block.

Thanks again,
Tom Larsen
