Whoops. I must've stopped reading that sentence when I got to the premise, "To make a complete formula bold", because I wasn't interested in making the whole formula bold, just the one symbol. I just read http://www.tex.ac.uk/cgi-bin/texfaq2html?label=boldgreek Seems like \mathbf is an anachronism. If \boldsymbol covers all uppercase Greek letters and thus completely subsumes the use case for \mathbf, then perhaps \mathbf shouldn't be so easy to access in LyX.
