Question: How do I get a complete list of the available arguments to \addtobeamertemplate?
Background: I want to modify the footline template in the Frankfurt theme. I found some sample code at How to insert page number in Beamer navigation symbols? that looks helpful:
\addtobeamertemplate{navigation symbols}{}{%
\usebeamerfont{footline}%
\usebeamercolor[fg]{footline}%
\hspace{1em}%
\insertframenumber/\inserttotalframenumber
}
Googling \addtobeamertemplate I see other arguments: frametitle, footline, title page. In the Beamer documentation I see frame begin and frame end (p. 63), headline (p. 64), and logo (p. 74).
How do I get a complete list of the available arguments to \addtobeamertemplate?
