Where can I find the \fontfamily names corresponding to the fonts I know?
I use beamer. Occasionally I want to use a particular font for the titles. I might use
\setbeamerfont{title}{family=\fontfamily{ppl}\selectfont}
to select the Palatino font that I know as \usepackage{mathpazo}. How/where can I find all the possible \fontfamily arguments and which font packages they correspond to?
