As a first trigger to get familiar with the trigger interface, we create one of the most basic triggers, the pressing of a specific key on a keyboard.
We create this trigger on a Player. The process for a trigger on a Campaign is vastly the same.
- Go to the Triggers and Interactivity menu of your Player.

- On the top-right, click on the orange Add Trigger button.

- Trigger settings look like this at the beginning.

- You can give the trigger a name. It is optional, but doing so will allow you to track this trigger in your playback reports later. Let's give this trigger the name “key 1” because we want content to trigger when a user presses the 1 on the attached keyboard.

- This is the When rule you have to set up. Click on the + button to add a trigger rule.

- As explained in the Introduction to Triggers and Interactivity tutorial, you can choose between many types of triggers. Here, let's choose “Key press”.

- As the content should get triggered when a user presses the 1, write “contains 1”.

- Next is the Action setting, meaning what shall happen when the trigger rule is performed. Click on the + button to add a trigger.

- The Action can be Play, Enqueue, Enqueue and Play, or Stop a content.

- This is further explained when you click on the question mark next to Action.

- Play: The content plays immediately and interrupts any currently playing content.
- Enqueue: The content plays next after the currently scheduled content has finished, but doesn't interrupt it.
- Enqueue and Play: The currently playing content is immediately interrupted. The queued content starts to play.
- Stop: It stops currently playing and queued content.
- To keep it simple, let's use Play. After making your Action choice, a window with your Content opens. Click on a piece of content and confirm with the orange “Select” button at the bottom.

- By default, the trigger is filled out to play in the Playing Loop and for 10 seconds, provided the content does not have its own duration.

- Click on the green check mark on the right. Your trigger will be sent to the Player, ready to be used on the next key press by a user.

There are additional trigger settings which we have left out. For further reading please see this tutorial.
