konsole "default" font

Hello... How does "konsole" get it's settings for "normal", "tiny", etc.? How can I change them? Somehow, my upgrade to 3.1.4 seems to have changed my default konsole font to some awful-ugly font, and I'd like to change it. Yes, I know that I can set it to a "custom" font, but I'd like to be able to change the whole "family", so that secting "large" or "medium" will change to a different font in the same family (or whatever word you'd use). I've tried grepping through .kde, etc., and I just can't figure out how to set it. Thanks much in advance! -Nick
