Sometimes an analysis calls for combining multiple events, but you might not know which events you need. You can explore event combinations directly in the chart controls without creating and saving a permanent custom event. Amplitude offers in-line OR logic to combine events for funnels and event segmentation charts.

Follow these steps to add a custom event:

1. Click _More Options_ in the _Events_ side control and select _Combine events inline_.

2. Click _Add event inline_ to add a custom event. Add any number of custom events.

{% callout type="note" %}
   The in-line event you create is relevant to that specific chart and isn't accessible anywhere else unless you save it as a custom event.
{% /callout %}

3. To add event properties, hover on the event and click _Filter_. Add as many filter properties as needed for each in-line event.

4. To use the in-line events in other charts, save them as a [custom event](/docs/analytics/charts/group-events). Click **More Options** and choose _Save Custom Event_.

5. Click _Remove_ to remove properties and in-line events.

{% callout type="note" heading="" %}
Custom events can't contain other custom events. Also, _Show User Journeys_, _Explore Conversion Drivers_, and _Show User Paths_ aren't available from the Microscope for in-line event steps in funnels.
