# Future Triggers

{% hint style="info" %}
Some triggers, like timer and exit-intent triggers are defined on the modal directly. Others are defined on separate elements such as button elements. 
{% endhint %}

SA5 supports both manual triggers automatic triggers.  

* Manual triggers are intentionally invoked by the user as part of the user flow, and will be invoked even if the user repeats that flow multiple times.
* Automatic triggers occur outside of the user action, and should not occur again if the modal has already been invoked ( manually or automatically ).

{% hint style="info" %}
Multiple triggers can be applied to the same modal, for example, two button triggers, a timer, and a scroll trigger can all invoke the same modal. To support this, the attributes for each trigger type are discrete ( see below ).&#x20;
