Instead of forking over over \$30 for a new remote to use for presentations, I found mira a little System Preference pane that lets me map the buttons on my brand new MacBook Pro’s remote to other applications. It took about 45 seconds of fiddling to get forward/back mapped to the up and down arrows and voila, I have a presentation remote.\
I love Mac developers. If I’ve got a problem, there’s usually a beautifully designed easy to use solution already out there.
