Konqueror "autoscroll" speed?

Anyone know how to adjust the speed that the page scrolls, when pressing "shift+downarrow" in Konqueror? I'm using a number of different machines with different SuSE/KDE versions, so any info on KDE 3.1 and up is interesting... It's a nice feature, but I don't read as fast as those who coded it do... I guess... :P TIA /Jon -- Just say "know!"
