Unfavouriting a track

[vometia]

Apologies for the rather ugly invented word!  And perhaps inept question: though I've been using Rockbox on my Sansa Clip for years, I've never really properly looked into what it can do.  But this has been irritating me.

Is there any way of flagging a track as "auto-skip", so if I'm playing a whole album, it excludes that "one duff track" that seems to be compulsory?  I use ogg format if it makes any difference.

I'm guessing the answer is to create a play-list, and that probably the easiest way to create a play-list is to use a text editor on my host system (typically something running a Unix) but I figured I'd ask just to see what my options were.  I have searched but I'm somewhat hamstrung in that I'm not even 100% certain what I'm looking for.

Thanks in advance!
