# Writing Beamer presentations in org-mode

## Introduction

### Overview

This presentation provides an illustration of some of the capabilities of the Beamer export in org mode:

1. simple slides (this one),
2. slides with special blocks,
3. multi-column slides and
4. the use of Babel for literate programming.

This file should be exported using M-x org-export-dispatch specifying l for \LaTeX{} and then P, for instance, to generate the PDF.

## Methodology

### A simple slide

This slide consists of some text with a number of bullet points:

• the first, very important, point!
• the previous point shows the use of bold emphasis which is translated to a \alert{} directive in \LaTeX.

The above list could be numbered or any other type of list and may include sub-lists.

### A more complex slide

This slide illustrates the use of Beamer blocks. The following text, with its own headline, is displayed in a block:

• Org mode increases productivity   B_theorem
• org mode means not having to remember \LaTeX commands.
• it is based on ASCII text which is inherently portable.
• Emacs!

### Two columns

• A block   BMCOL
• this slide consists of two columns
• the first (left) column has no heading and consists of text
• the second (right) column has an image and is enclosed in an example block
• A screenshot   B_example BMCOL

### Babel

This slide shows some code and resulting output using Babel. Note the specification of BEAMER_act property for the second column.

• Octave code   BMCOL B_block
A = [1 2 ; 3 4]
b = [1; 1];
x = A\b

• The output   BMCOL B_block
A =

1   2
3   4

x =

-1
1



## Conclusions

### Summary

• org is an incredible tool for time management
• but it is also excellent for writing and for preparing presentations
• Beamer is a very powerful \LaTeX{} package for presentations
• the combination is unbeatable!
