# FX Input Trigger
An FX Input trigger waits for an input switch to be activated on a Stagehand FX, then starts the following step.
## Editing
After you have [added a fx input trigger](/docs/spikemark-6/cues/cue-creation/add-triggers.md) click it to open the trigger editor.
* Select the FX that you want to monitor from the "Fx" dropdown list.
* Enter the target input in the "Watch Input" field.
* Click the "Save Changes" button to save your changes.
{% hint style="info" %}
The trigger becomes armed when the step starts. If the input is activated before the step starts, the trigger will not fire.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.creativeconners.com/docs/spikemark-6/triggers/fx-input-trigger.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
