Users are unable to type the letter 'S' into fillable PDF forms stored on SharePoint because the keystroke triggers a share menu.

How to Fix SharePoint PDF Forms Opening Share Dialog When Typing 'S'

Product: SharePoint / PDF Viewer
Device & OS: not provided
Scenario: Filling out interactive PDF forms directly within the SharePoint web-based document viewer.
Observed behavior: Pressing the 'S' key inside a form field incorrectly opens a 'Share' pop-up dialog box instead of typing the character, blocking normal data entry.

Before you start

Ensure your browser is updated to the latest version and temporarily disable any browser extensions to rule out third-party script conflicts.

Solution 1Recommended

Download the PDF and Edit Locally

Since this is a web viewer shortcut conflict, downloading the file to your computer allows you to bypass the browser issue entirely.

Opening the PDF in a dedicated desktop application circumvents the keyboard shortcuts forced by the SharePoint web interface. This is the most reliable workaround until a permanent fix is deployed.

Select the PDF

In your SharePoint document library, hover over the affected PDF form and click the three-dot menu (Show actions) next to the file name.

Download the file

Select 'Download' from the dropdown menu to save the PDF file directly to your local computer.

Open in a desktop app

Open the downloaded file using a dedicated desktop PDF editor, fill out the form normally, save your changes, and re-upload the finalized document to SharePoint.

Data Integrity: Editing locally ensures no form data is lost due to unexpected browser refreshes or shortcut bugs.

Solution 2

Test Browser Extensions and Caches

Sometimes third-party browser extensions or corrupted cache data can interfere with SharePoint's default keyboard shortcuts.

Frequently Asked Questions

Why does typing 'S' open the Share menu in SharePoint?

This is a known keyboard shortcut bug that was reported by multiple users starting in June 2024. The web-based PDF viewer mistakenly interprets the 'S' keystroke inside a text field as a global command to open the document's Share dialog.

Can I disable SharePoint keyboard shortcuts to fix this?

Currently, SharePoint does not offer a native settings toggle to disable this specific Share shortcut in the web-based PDF viewer. The best immediate workaround is to download the file and edit it in a local PDF application.

Does this issue happen on all web browsers?

Users have reported experiencing this 'S' key conflict across multiple major web browsers, including Microsoft Edge and Google Chrome, indicating the issue stems from the SharePoint viewer's scripting rather than a specific browser engine.
