<p>In addition to being associated with pointer devices, the <a class="eventtype" href="#event-type-click"><code>click</code></a> event type must be dispatched as part of an element activation, as described in <a href="#event-flow-activation">Activation triggers and behavior</a>.</p>
- <p class="note" id="click-activation"><strong>Note:</strong> For maximum accessibility, authors should use the <a class="eventtype" href="#event-type-click"><code>click</code></a> event type when defining activation behavior for custom controls, rather than other pointing-device event types such as <a class="eventtype" href="#event-type-mousedown"><code>mousedown</code></a> or <a class="eventtype" href="#event-type-mouseup"><code>mouseup</code></a>, which are more device-specific.</p>
