-  Currently, you should \emph{not} use this option. Only bitmapped

+  Use this option only with fonts that have outline fonts available in
+  the T1 encoding like Times or the lmodern fonts. In a standard
+  installation the standard Computer Modern fonts (the fonts Donald
+  Knuth orginally designed and which are used by default) are
+  \emph{not} available in the T1 encoding. Using this  option with
+  them will result in very poor rendering of your presentation when
+  viewed with \pdf\ viewer applications like Acrobat or |xpdf|. To use
+  the Computer Modern fonts with the T1 encoding, use the package
+  |lmodern|.  See also Section~\ref{section-font-encoding}.
+  The package switches to a T1~encoding, but it does not redefine all
+  fonts such that outline fonts (non-bitmapped fonts) are used by
+  default. For example, the sans-serif text and the typewriter text
+  are not replaced. To use outline fonts for these, write

-\subsubsection{Serif Fonts and Sans Serif Fonts}
+\subsubsection{Serif Fonts and Sans-Serif Fonts}
 By default, the beamer class uses the Computer Modern sans-serif fonts
 for typesetting a presentation. The Computer Modern font family is the
   impression, which might be exactly what you wish to create.
-You must decide whether the text should be typeset in sans serif or in
+You must decide whether the text should be typeset in sans-serif or in
 serif. To choose this, use either the class option |sans| or
 |serif|. By default, |sans| is selected, so you do not
-need to specify this. Furthermore, you can specify one of the two
-options |mathsans| or |mathserif|. These options
-override the overall sans-serif/serif choice for math text.

   Use a serif font during the presentation.
+\subsubsection{Fonts in Mathematical Text}
+By default, if a sans-serif font is used for the main text,
+mathematical formulas are also typeset using sans-serif letters. In
+most cases, this is visually the pleasing and easily readable way of
+typesetting mathematical formulas. However, in mathematical texts the
+font used to render, say, a variable is sometimes used to
+differentiate between different meanings of this variable. In such
+case, it may be necessary to typeset mathematical text using serif
+letters. Also, if you have a lot of mathematical text, the audience
+may be quicker to ``parse'' it, if it typeset in the way people
+usually read mathematical text: in a serif font.
+You can use the two options |mathsans| and |mathserif| to override the
+overall sans-serif/serif choice for math text. However, using the option
+|mathsans| in a |serif| environment makes little sense in my opinion.
   Override the math font to be a sans-serif font.
   Override the math font to be a serif font.
+The command |\mathrm| will always produce upright (not slanted), serif
+text and the command |\mathsf| will always produce upright, sans-serif
+text. The command |\mathbf| will produce upright, bold-face,
+sans-serif or serif text, depending on whether |mathsans| or
+|mathserif| is used.
+To produce an upright, sans-serif or serif text, depending on
+whether |mathsans| or |mathserif| is used, you can use for instance
+the command |\operatorname| from the |amsmath| package. Using this
+command instead of |\mathrm| or |\mathsf| directly will  automatically
+adjust  upright mathematical text if you switch from sans-serif to
+serif or back.
 \subsubsection{Font Families}
 Independently of the serif/sans-serif choice, you can switch the
 installation. For this reason, using the T1~encoding will produce
 \pdf\ files that render very poorly.
-I recommend that you use the standard OT1 encoding and remove
-|\usepackage[T1]{fontenc}| if present. Hyphenation should
-no occur in a presentation anyway. If you really have to hyphenate,
-you should do so by inserting a hyphenation point using the
-command~|\-| as for example in |haplo\-typing|.
+Most standard PostScript fonts are available in T1~encoding. For
+example, you can use Times in the T1~encoding. The package |lmodern|
+makes the standard Computer Modern fonts available in the
+T1~encoding. Furthermore, if you use |lmodern| several extra fonts
+become available (like a sans-serif boldface math) and extra symbols
+(like proper guillemots).
