Microsoft is adding a prompt input directly to the Copilot button in Word, Excel and PowerPoint. Message Center post MC1470885 says users can type or dictate what they need and reference Microsoft 365 content without first opening the full Copilot pane. The update changes where a request begins inside the application, bringing it closer to the content on screen.
The capability is associated with the Dynamic Action Button and is rolling out to Windows desktop, macOS and web applications. Worldwide general availability began in September 2026 and is expected to finish by the end of December 2026. Platforms need not receive it simultaneously, so a different-looking button on one computer does not establish a problem with another account.
A request inside the document, with relevant context
Selecting content in Word or PowerPoint also brings up a contextual input box with suggestions such as Rewrite and Shorten. It provides a shortcut for requests to rephrase or shorten material. Note the distinction between the applications covered by the overall update and this example: the contextual selection box is described for Word and PowerPoint, rather than a promise of an identical interface in Excel.
Direct input can suit a focused change, such as shortening a passage while preserving its meaning. Specify what must remain: numbers, names, tone or a conclusion. A ready-made suggestion does not remove the need to review the output. Even a small shortening should be checked for lost qualifications or changed details. That is ordinary editorial review, whether the request comes from a small button or a full pane.
The keyboard shortcuts are Alt+C on Windows and Command+Control+I on Mac. They offer another route to Copilot within the workspace. A shortcut's existence does not establish that an account is entitled to every capability: the update applies to eligible users as rollout reaches their platform.
What organization administrators need to know
Microsoft's notice says the feature is enabled by default for eligible users and requires no administrator action. Existing Copilot controls continue to apply, and there is no separate administrative control for this input box. The interface change should therefore not be treated as removal of organizational policy or a new permission to access all Microsoft 365 content.
Internal support teams should distinguish a visual change, account eligibility and an ongoing rollout. Work instructions can be updated to explain the prompt box and shortcuts. For users, the test is straightforward: can they request the required action without losing the document's context? If so, the button saves an interface transition; it does not replace professional review of the result. Make sure team instructions also describe the platform people actually use.
