I decided to map konqueror to one of the extra buttons in my so-called "multimedia" keyboard. The problem is that if I press the button too long several instances of konqueror are started. Is there an option I can pass to konqueror or a config file setting that I can set that will prevent one konqueror session from starting if one is already running. I'm thinking of something like a "--server" option that will force the program to just connect to an existing session.
