• navigate the presentation with n/f, p/b
• go to a specific page with v <num> RET
• scroll with k and l

Showing another file

It is sometimes useful to show an additional file. This could be done with the usual Emacs commands, but sometimes a more “polished” look is desirable in a presentation. Epresent supports splitting the window to show a file in a new buffer. This functionality is activated by the i key during the presentation, and it can be tested invoking M-x epresent-show-file outside of the presentation. The filename is set through the property EPRESENT_SHOW and the file is showed by default to the right of the presentation buffer. It can be shown under the presentation by setting the property EPRESENT_BELOW to a non-nil value. To hide the file again, delete the window as usual with C-x 0.

Here is an example:

* My slide 
  :PROPERTIES:
  :EPRESENT_SHOW: myfigure.pdf
  :EPRESENT_BELOW: t
  :END:

Any file that can be opened in Emacs can be shown in this way. For example, a PDF with multiple pages can be used to show more than one figure in a sequence.
