- Product
- Acrobat Online Services
- Device & OS
- not provided
- Scenario
- Reading and navigating a PDF document online through a web browser.
- Observed behavior
- Pressing the up or down arrow keys does not scroll the document, requiring alternative navigation methods to view the rest of the file.
Verify that your keyboard is functioning properly in other applications and ensure that your web page has fully loaded before attempting to scroll.
Restore Browser Focus to the Document Viewer
Often, the browser loses active focus on the PDF area, meaning keyboard commands are ignored. Clicking inside the viewer usually resolves this instantly.
Web browsers contain multiple active zones, such as the URL bar, bookmarks, and the main display area. If you recently clicked a browser menu or opened a new tab, the keystrokes might not register in the Acrobat online viewer until you refocus it.
Hover your mouse over the actual PDF page displayed on your screen and click once anywhere on the document text or background.
Press the Up or Down arrow keys on your keyboard to see if the document resumes scrolling.
If the arrow keys are unresponsive, try pressing the Page Up or Page Down keys, or click and drag the browser's native scroll bar on the right side of the window.
Disable Interfering Browser Extensions
Browser extensions can sometimes hijack keyboard shortcuts or disrupt how web-based applications process keystrokes.

Frequently Asked Questions
Why does clicking inside the PDF viewer fix keyboard scrolling issues?
Web browsers can easily lose active focus on embedded elements like a PDF viewer if you click on the address bar, switch tabs, or interact with a toolbar. Clicking directly on the PDF restores focus, ensuring your browser sends your keystrokes to the document rather than the browser window itself.
Can ad blockers stop my arrow keys from working in PDFs?
Yes, some ad blockers or privacy extensions run scripts that can inadvertently block or intercept normal JavaScript execution on web pages. This might prevent a web-based PDF viewer from accurately detecting and processing keyboard commands.
Are there other keyboard shortcuts for scrolling PDFs online?
If arrow keys fail, you can usually use the Page Up and Page Down keys to jump by screen length. Additionally, pressing the Spacebar generally scrolls down one page, while holding Shift + Spacebar scrolls up one page.
