- Scenario
- Viewing and navigating pages using the Page Thumbnails sidebar panel.
- Observed behavior
- Adobe Acrobat displays a small black square for the currently viewed page and a blue highlight for the selected thumbnail. There is no built-in setting to customize the black indicator's color or size.
Ensure you have the Page Thumbnails navigation pane open in Adobe Acrobat to view the page indicators properly.
Identify the Different Page Indicators in the Thumbnails Panel
Understand how Adobe Acrobat uses different visual cues to indicate viewed versus selected pages, as customization is limited.
Adobe Acrobat uses two distinct indicators within the Page Thumbnails panel to help you navigate your document.
Currently, Acrobat does not provide a native setting to change the color, size, or visibility of the black page-view indicator. Understanding how these indicators function is the best way to navigate your document effectively.
Look for a small black square inside the Page Thumbnails panel. This square strictly indicates the page you are currently viewing in the main document window.
Click on any thumbnail in the panel. It will outline in a blue highlight, which indicates that the specific thumbnail is selected for editing or extraction, even if you are actively viewing a different page.
