Suppose I wanted to use a different font for a title then the body text in LaTeX (pdflatex). (For example, if I wanted to use a slightly fancier font for titles, or a sans-serif one.) How would I do that, change the font of a class of thing throughout the document, in a proper way. (Likewise, if I wanted to change the document title, captions, etc. Is there a general way of doing this?)


Question: Can I use an Apple remote to control a keynote presentation?
Answer: Yes - although most people are using the iOS based Keynote Remote these days, the old infrared (which is very thin / physically touchable and very reliable in dark rooms and easily hidden in a hand) works just fine.

The Keynote '09 help shows what functions the various buttons will perform when you are in the various modes: Keynote window itself, presentation mode and slide switcher mode.
