-\beamer's font mechanism is somewhat similar to \beamer's color mechanism, but not quite the same. As for colors, every \beamer\ element, like the frame titles, the document title, the footnotes, and so on has a certain \beamer-font. As for colors, on the one hand you can specify the font of each element individually; on the other hand fonts also use inheritance, thereby making it easy to globally change the fonts used for, say, ``titlelike things'' or for ``itemizelike things.''

 While a \beamer-color has a certain foreground and a certain background, either of which may be empty, a \beamer-font has a size, a shape, a series, and a family, each of which may be empty. The inheritance relation among \beamer-fonts is not necessarily the same as between \beamer-colors, though we have tried to match them whenever possible.

   A color theme only dictates which colors are used in a presentation. If you have chosen a particular presentation theme and then choose a color theme, only the colors of your presentation will change.

+  A font theme dictates which fonts or font attributes are used in a presentation. Similar to colors, the font of all text elements used in a presentation can be specified independently.
 \item[Inner Themes]
   An inner theme specifies how certain elements of a presentation are typeset. This includes all elements that are at the ``inside'' of the frame, that is, that are not part of the headline, footline, or sidebars. This includes all enumerations, itemize environments, block environments, theorem environments, or the table of contents. For example, an inner theme might specify that in an enumeration the number should be typeset without a dot and that a small circle should be shown behind it. The inner theme would \emph{not} specify what color should be used for the number or the circle (this is the job of the color theme) nor which font should be used (this is the job of the font theme).

 For the PostScript version and for printing multiple slides on a single page this simple approach does not work. In such cases you can use the |pgfpages| package, which works directly with |pdflatex|, |lualatex|, |xelatex| and |latex| plus |dvips|. Note however \emph{that this package destroys hyperlinks}. This is due to fundamental flaws in the \pdf-specification and it is not likely to change.
