this seems like a stupid question, but how do I control what programs org uses when it launches an exported file in an external viewer? I keep getting galeon for html, okular for pdf, which on my system are two buggy programs I otherwise never use. They don't get launched by, say, nautilus or firefox, so I figure the setting must be somewhere in emacs or org, but i can't figure out where. Thanks much! Matt -- Matt Price matt.price@utoronto.ca
