The $list widget filter, [tag{!!title}tag[CAD]], only produces output when
there are matching tiddlers. If there are more than one match, the body of
the widget is output multiple times. By adding limit[1] to the filter the
body will only be shown once.
Note: rather than referencing {!!title}, the filter could also have been
written as [tag<currentTiddler>tag[CAD]], which perhaps more clearly shows
how the currentTiddler's title is being used.
Adding the variable="..." parameter to the $list widget assigns the
matching tiddler's title to the specified variable name. For this
particular use-case, you don't actually need to reference this variable
inside the $list body; it is only used to prevent the $list widget from
changing the value of <currentTiddler>. Thus, the name of the variable
isn't important and I have used it simply to describe the purpose of the
"test" filter.
Hope this explains things...
