Thanks for the CLI-command tip! =:^)

There are related, but less detailed settings in kcontrol (wrongly aka 
systemsettings).  It seems the kde folks are pulling a gnome and deciding 
their users are too dumb to be exposed to the full set of options by 
default, so they're hiding them in an off-menu location, where only those 
knowing about the command-line app can access them.

FWIW, the (apparently) parallel kcontrol/systemsettings location is (for 
kde 4.5+), common appearance and behavior, application appearance, the 
style applet.  On the applications tab, if oxygen is chosen as the widget 
style and one clicks the configure button, a similar but as I mentioned 
less detailed dialog pops up.  Additionally, on the fine-tuning tab, I 
expect the graphical effects drop-down sets general not-oxygen-specific 
parameters that oxygen in turn uses to set defaults for entire groups of 
the settings available in oxygen-settings, at once.
