# Keystroke markers

Keystroke markers are an easy way to manually add event data into your data stream if high temporal precision of these markers is not a priority.

Keystroke marker settings are saved to your local device.

#### How to add markers to your EEG data stream while recording

There are two ways you can add event markers to an EEG data stream recording:

**Typing the number associated with the event**\
To add markers to your EEG data stream while recording, type the number associated with the marker on your keyboard at the time of the event. When you type the number, a vertical pink line will appear in the data stream.&#x20;

**Adding a marker with a mouse click**\
To add a marker to an EEG data stream recording with a mouse click, you need to:

1. Open the keystroke marker configuration legend (to do this, see How to open the keystroke marker configuration legend).&#x20;
2. Place the legend in a suitable place on the screen.&#x20;
3. Each time you need to mark an event in an EEG data stream, click on the appropriate keystroke marker in the legend. You’ll then see a pink vertical line appear in the data stream to mark the event.  &#x20;

You can add markers to Raw EEG, Performance Metrics, and Motion views, so you can easily see the event when you review the recorded EEG data.\
