[Tex/LaTex] Add Footer Text to All Slides in Beamer

Question

Is there a way to append footer text to the slides in beamer? I wanted to get rid of the default footer, but I want to add a bit of additional text. Right now I have:

%gets rid of bottom navigation bars
\setbeamertemplate{footline}[page number]{}

%gets rid of navigation symbols
\setbeamertemplate{navigation symbols}{}

Answer 1

Section 8.2.1 The Headline and Footline of the beameruserguide lists the predefined inserts that can be used to add information to the footline template. If you want to add some additional information (not covered by the listed inserts), you can use the text line option for the footline template.

A little example in which "some text" is added as well as the short name of the author centered and the page number flushed to the right (I used a \parbox with some negative vertical skip to shift the information a little bit upwards):

\documentclass{beamer}

\setbeamertemplate{footline}[text line]{%
  \parbox{\linewidth}{\vspace*{-8pt}some text\hfill\insertshortauthor\hfill\insertpagenumber}}
\setbeamertemplate{navigation symbols}{}
