How do you find the names of settings?

[Frankenpod]

%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.

Have a look at the manual. There's a chapter called "config file options"

Thanks, that's essentially the list I was looking for.  But, ironically, Perceptual Bass Enhancement and one-or-two other settings are not included.
Perhaps because it's a new(ish) feature?

It looks like the author added a description in the manual, but didn't list the new settings.

I think the setting you want is "pbe";

I find it easier to just tweak a setting and see what changes in .rockbox/config.cfg
