Since Org’s Beamer export back-end is an extension of the LaTeX back-end, it recognizes other LaTeX specific syntax—for example, ‘#+LATEX:’ or ‘#+ATTR_LATEX:’. See LaTeX Export, for details.
Beamer export wraps the table of contents generated with ‘toc:t’ ‘OPTION’ keyword in a ‘frame’ environment. Beamer export does not wrap the table of contents generated with ‘TOC’ keyword (see Table of Contents). Use square brackets for specifying options.
#+TOC: headlines [currentsection]
Insert Beamer-specific code using the following constructs:
#+BEAMER: \pause #+BEGIN_EXPORT beamer Only Beamer export back-end exports this. #+END_EXPORT Text @@beamer:some code@@ within a paragraph.
Inline constructs, such as the last one above, are useful for adding
overlay specifications to objects with bold, item, link,
radio-target and target types. Enclose the value in angular
brackets and place the specification at the beginning of the object as
shown in this example:
A *@@beamer:<2->@@useful* feature
Beamer export recognizes the ‘ATTR_BEAMER’ keyword with the following attributes from Beamer configurations: ‘:environment’ for changing local Beamer environment, ‘:overlay’ for specifying Beamer overlays in angular or square brackets, and ‘:options’ for inserting optional arguments.
#+ATTR_BEAMER: :environment nonindentlist - item 1, not indented - item 2, not indented - item 3, not indented
#+ATTR_BEAMER: :overlay <+-> - item 1 - item 2
#+ATTR_BEAMER: :options [Lagrange] Let $G$ be a finite group, and let $H$ be a subgroup of $G$. Then the order of $H$ divides the order of $G$.
