[NTG-context] documentation: parameters of \setuplist

I tried to complete https://wiki.contextgarden.net/Command/setuplist, but I don’t understand all parameters. Can anyone explain these please: * state (start stop): what does this en-/disable? collecting entries? * label (yes no none Name): language dependent labels? as a prefix or what? * location (none, here): disable placement? when makes this sense? * aligntitle (yes no): align which part to what? * symbol (one two three none default): where is this used? Expect more questions… Hraban
