-= Using Search Box
+= Using Command Palette
 
-Every page in Jenkins has a search box on its top right that lets you get to your destination quickly, without multiple clicks.
+Jenkins now features a new search experience known as *Command Palette*.
+Located in the upper-right corner of the page next to your name, the Command Palette enables you to search everything in Jenkins.

-For example, if you type "foo #53 console", you'll be taken to the console output page of the "foo" job build #53.
-If you have "XYZ" view, just type "XYZ" to get to that view.
-The search box comes with auto-completion to assist you.
+For example, enter "git #23 console" to display the results for the console output page of "git job build #23".
+The Command Palette feature utilizes auto-completion to help you find what you're looking for.
+Results can include additional search terms for narrowing results, Pipelines, Views, additional features installed within your Jenkins environment, such as the Design Library, and specific pages within jobs based on your installed plugins, such as the plugin:warnings-ng[Warnings] plugin.
+Search results also provide more clarity in the form of icons to help indicate Jenkins features and job statuses.

+The Command Palette is also accessible via keyboard commands for macOS (`CMD+k`) and Windows/Linux (`CTRL+K`).
 
-The search box is also context sensitive.
-If you are already somewhere in the foo job (perhaps you are looking at another build), then you can just type "#53 console" instead of "foo #53 console".
-If you are already somewhere in the foo #53 (maybe you are looking at test report), then you can just type "console" to get to the same page.

 [[SearchBox-OpenSearchsupport]]
 === OpenSearch support
 
-This search box feature is also exposed to the browser through http://en.wikipedia.org/wiki/OpenSearch[OpenSearch], so you can install this search and auto-completion feature to your browser search box. This would further reduce the overhead it takes for you to visit a particular page in Jenkins.
+This search feature is also exposed to the browser through http://en.wikipedia.org/wiki/OpenSearch[OpenSearch], so you can install this search and auto-completion feature in your browser search box, making it even easier to navigate Jenkins.
 
 For example in Firefox, you can add the Jenkins search to your browser's search engines via the dropdown on the right of the address bar:
