I don't think this is the simplest way to do this, Pete. (See my answer.)

You need "elevated privileges", and again to switch it off and on. And therefore, for this ability and simplicity, I recommend system-wide.

To switch it off execute this: "sudo mv /usr/local/texlive/texmf-local/ls-R /usr/local/texlive/texmf-local/ls-R-on ; sudo mv /usr/local/texlive/texmf-local/ls-R-off /usr/local/texlive/texmf-local/ls-R", to switch it on: "sudo mv /usr/local/texlive/texmf-local/ls-R /usr/local/texlive/texmf-local/ls-R-off ; sudo mv /usr/local/texlive/texmf-local/ls-R-on /usr/local/texlive/texmf-local/ls-R"!
