# About the Coveo UI pipelines
The Coveo UI pipelines are used to handle UI and control-specific events either in the Page Editor, Content Editor, or a standard Coveo-powered search page.

Again, they're somewhat less frequently customized than the indexing and search pipelines.
You can find them in the `/configuration/sitecore/pipelines` section of the `Coveo.UI.Controls.config` file.

The following table is a summary of all those pipelines:

[%header,cols="5"]
|===
|Pipeline
|Purpose
|Description
|Processors included by default
|Is typically customized?

|`saveDatasource`
|Data source management
|Used to edit the data source of the current rendering.
|`Coveo.UI.PipelineProcessors.SaveDatasource.Save`
|[x]

|`uiGetMasters`
|Insert options management
|Used to define which insert options should be available in the Content Editor (see [All About Insert Options](https://community.sitecore.com/community/en/all-about-insert-options-in-the-sitecore-asp-net-cms?id=community_blog&sys_id=8ed2a7ed1b8370d0b8954371b24bcba8)).
In the context of Coveo for Sitecore, this is used to allow the Coveo-powered search page template (along with its MVC version) to appear within the available insert options under the /sitecore/content node.
|`Coveo.UI.PipelineProcessors.GetMasters.AllowSearchPageProcessor`
