<ul>
    <$list filter="[tag[Meeting]!sort[at]]">
        <li><$link to=<<currentTiddler>>><<currentTiddler>></$link></li>
    </$list>
</ul>

Since this is such a common pattern, TiddlyWiki offers several ways to abbreviate it. If the text of the link should be be the same as the target, you can leave the body empty using a self-closing tag:

<$link to=<<currentTiddler>>/>

And in fact, if the target should be the current tiddler, you can just say:

<$link />

We'll be seeing much more of using <<things in angle brackets>> as attribute values in widgets and HTML tags when we learn about transclusion in the next chapter.
