# LaTeX beamer slideshow presentation

When I export a beamer presentation, I get a .pdf file. Now I want to present it slide by slide like a powerpoint slideshow presentation, but I'm not sure what the best way to do so is. I can't find a feature that allows me to open up a slide to fit the whole screen and then click through my presentation with the space bar. Is there a feature like this somewhere?

P.S. I looked through Is there a nice solution to get a "presenter mode" for Latex presentations?, but this seems too complex (i.e., I just need a "click the space bar to go from one slide to another" kind of advice).

• In Adobe Acrobat simply press <Ctrl>-<L> for the full-screen presentation mode. – Uwe Ziegenhagen Dec 27 '14 at 7:08

I can't find a feature that allows me to open up a slide to fit the whole screen

Almost any PDF viewer have in the view menu a "Full Screen Mode", "Presentation mode" or something similar,as well as shortcuts as Ctrl+L (Acrobat Reader), F5 (Evince) or Crtl+Shift+P (Okular).Just search in the menu.

But if you want start in this mode to avoid delays in front of the audience, you can use the option pdfpagemode=FullScreen of the hyperref package (already loaded by the document class):

\documentclass{beamer}
\hypersetup{pdfpagemode=FullScreen}
\begin{document}
Hello,World
\end{document}


This way, assuming that you open the PDF with Acrobat Reader (e.g.:acroread file.pdf) it should be showed in the whole screen without Ctrl+L, although this and others viewers as okular will ask for confirmation the first time. Others as xpdf simply ignore this option. Others as evince simply do the job. Others as impressive (really a presentation tool, not a simple pdf viewer) show any PDF in full screen mode, with or without this option.

and then click through my presentation with the space bar.

This is the usual behavior in presentation mode with any PDF viewer (space bar = next page).

• The exported output (.pdf) file is the same with or without this option. Could you please explain? – warship Dec 29 '14 at 7:45
• @warship. Not really the same. Please see the edited answer. – Fran Dec 29 '14 at 9:41
• Thank you for the (important) distinction between PDF viewer and presentation tool (like impressive)! – JJoao Dec 29 '14 at 13:27
• @Fran I use Preview (I'm on Mac OS X) instead of Acrobat Reader and do not have the acroread command in my command line utilities. In Preview, the \hypersetup{pdfpagemode=FullScreen} does not alter the final outcome. Any suggestions? – warship Dec 30 '14 at 0:23
• @warship, I have no experience with Mac OS X, but Acrobat Reader is available also for this OS. Moreover, you can try with the many free PDF viewers for Mac (see here for example). – Fran Dec 30 '14 at 5:13

If you are using TexMaker 5.0.3(64 bit) there is an eye icon immediately after the zoom out icon. You click that and a drop down menu appears. Click on presentation and it will open in presentation mode.
