Hand-writing annotations on Keynote or PDF slides For teaching purposes I would like to be able to handwrite on slides as I give a presentation, ideally with a Wacom graphics tablet which I already own.
Powerpoint would work really well for this, unfortunately I am using Keynote to make the slides because I need the LaTeX support which Powerpoint doesn't have. So in particular I can't easily convert these slides to Powerpoint.
I can convert them to PDF, though. Is there a good way to annotate slides during a presentation for either a Keynote or PDF presentation?
EDIT: In Preview, I can annotate the document but only when it's not in Presentation mode.
Preview has a sketch function that you can use to “write” after a fashion.
I don’t possess a wacom graphics tablet so no idea how it would perform with that.
