[arch-general] How to change default terminal from xterm

On my desktop machine, it seems like any time a GUI app needs to launch a console app, the default is to launch it in an xterm window. But as I'm a hardcore KDE user, I'd like to change that default to konsole. Wasn't able to figure out where this setting is to override it, however. "set | grep xterm" didn't turn up much of relevance, and I couldn't see any KDE setting to override it either. Anyone know how to tweak this? Tnx, DR
