Find and Highlight for all occurrences of a word in one action, without using JavaScript, add to built-in functionality instead.

At this time, Adobe Acrobat does not have a native feature to automatically “Find and Highlight” all occurrences of a word in one action. While Acrobat does allow you to find text and manually highlight it, bulk highlighting across the document is not supported without using JavaScript.

The options you may notice such as “Find Text” under the Redaction tool are specifically designed for redaction workflows and cannot be used to apply highlight annotations. This is why only redaction-related actions appear in Custom Actions or advanced tools.

Automated highlighting is currently possible only through JavaScript-based solutions. Since JavaScript is restricted in your environment, there is unfortunately no supported workaround available at this time using Acrobat’s built‑in functionality.
