Ok, I think you can do it without the list widget using this instead of the
action-listops:
<$action-setfield $tiddler=<<tid>> $index="mode" $value={{{
[<tid>getindex[mode]compare:string:eq[author-mode]][<tid>getindex[mode]compare:string:eq[presentation-mode]]+[toggle[author-mode],[presentation-mode]]
}}} />
The thing thing is, I don't quite understand how toggle works, and I feel
either toggle is buggy or the documentation is. If you don't use it with
the +[xxx] construction, it will use the entire pool of tiddlers to output
at least one tiddler name. But it will put out exactly one tiddler name.
And what is the difference inside of a filter between a "list" and a "title
list" ?
At a very minimum, this line is grammatically incorrect: " If neither is
present, the first parameter takes precedence is added to the list."
(Probably wants an "and" before "is" )
