# Interactivity and Popups
The settings under the Interactivity tab of the layer editor give you some control over values that may appear when you click on a layer or hover over a layer feature. A Banner is short text that can be displayed toward the bottom of the map when the user hovers over features. Tootips are short text displayed next to the mouse cursor when you hover over a feature. Popups appear when you click feature.
Here I have entered "12nm Boundary" as a tooltip. Howevering my cursor over a feature in this layer reveals that text.
Note that Tooltips and Popups can be enhanced with simple HTML tags. We will provide more information on this feature in future updates to our documentation.

Remember, changes to these settings will only be updated after [Publishing Changes](/seasketch-documentation/administrators-guide/overlay-layers/publishing-changes.md)
