How to Keep the Highlight Tool Active in Adobe Acrobat
Product
Adobe Acrobat
Device & OS
not provided
Scenario
Highlighting multiple passages of text in a PDF document continuously for review or studying.
Observed behavior
The Highlight tool automatically turns off and becomes inactive after applying just one highlight, forcing the user to reselect the tool for every subsequent markup.
Before you start

Ensure your PDF document is not restricted from editing or commenting, and verify that you are accessing the specific 'Comment' toolbar rather than a quick-select menu.

Solution 1Recommended

Pin the Highlight Tool in the Comments Toolbar

Use the built-in Pin feature to keep the Highlight tool active for continuous use without reselecting.

Adobe Acrobat includes a specific toggle to lock annotation tools. When this is enabled, you can apply multiple highlights across your document without the cursor reverting to the default selection tool.

1
Open the Comment Toolbar

Launch Adobe Acrobat, open your PDF document, and select 'Comment' from the right-hand pane or the 'Tools' menu.

2
Select the Highlight Tool

Click on the 'Highlight text' tool icon located at the top of the Comment toolbar.

3
Click the Pin Icon

Look for the 'Keep tool selected' icon (which looks like a push pin) in the toolbar and click it to lock the highlight tool.

4
Highlight Continuously

Drag your cursor over the various text passages you want to highlight. The tool will now stay active for multiple selections.

Quick Tip: You can unpin the tool at any time by clicking the Pin icon again or simply pressing the 'Esc' key on your keyboard to return to the selection cursor.

Frequently Asked Questions

Why does my highlight tool keep turning off in Adobe Acrobat?

By default, Acrobat may revert to the selection tool after a single highlight to allow users to interact with other document elements safely. You must manually enable the 'Keep tool selected' (Pin) icon in the Comment toolbar to override this behavior.

Will repairing Adobe Acrobat delete my PDF files?

No, using the 'Repair Installation' option from the Help menu only scans and replaces missing or corrupted application files. Your personal PDF documents, comments, and data will remain safe.

How do I highlight multiple separate lines at once?

To highlight multiple unconnected lines, activate the highlight tool, click the 'Pin' icon to keep it selected, and then drag your cursor over each separate passage of text one by one.

What if the Pin icon is missing from my Acrobat toolbar?

If you cannot see the Pin icon, you might be using an outdated version of Acrobat or a simplified quick-tool menu. Ensure you open the full 'Comment' toolset from the right pane, or update the software via Help > Check for Updates.
