You can use a useful little trick to do this. The trick is that we can abuse the list widget into behaving like the reveal widget except that the condition for display is whether a filter returns any results or not.
The idea is to take advantage of the fact that the template of the list widget is rendered 0 or more times, depending on the number of items in the list. We can limit the number of results returned from a filter with the [limit[n]] filter operator. So, we can make filters that return 0 or 1 renderings of the template, just like the reveal widget. <$list filter="[is[current]next[Lesson1]limit[1]]" variable="listItem"> Next: <$list filter="[is[current]next[Lesson1]]"/> </$list> <$list filter="[is[current]previous[Lesson1]limit[1]]" variable="listItem"> Previous: <$list filter="[is[current]previous[Lesson1]]"/> </$list> If the list filter doesn't return any results then the list template isn't rendered at all. Setting the attribute variable to "listItem" prevents the default behaviour of setting the currentTiddler variable to the title of each list item, so that the current tiddler within the template is the same as that of the list filter itself.
