%St takes as argument the name of a setting.
But I can't find anywhere in the WPS custom screen documentation a list of the names of settings.
For some its easily guessable, e.g. "bass" and "treble". But what, for example, is perceptual bass enhancement referred to as? PBE? Perceptual? Perceptual_bass_enhancement? Perceptualbassenhancement?
Is there a list somewhere? Thanks.
