<a class="index-entry-id" id="index-traps_002c-diversion"></a>
<p>A diversion is not formatted in the context of a page, so it lacks page
location traps; instead it can have a <em class="dfn">diversion trap</em>. There can
exist at most one such vertical position trap per diversion.

<p>Set a trap <em class="emph">within</em> a diversion at location <var class="var">dist</var>, which is
interpreted relative to diversion rather than page boundaries. If invoked with
fewer than two arguments, any diversion trap in the current diversion is
removed. The register <code class="code">.t</code> works within diversions. It is an
error to invoke <code class="code">dt</code> in the top-level diversion.
