Understand Tool Selection Order in Acrobat Commenting
Adobe designed these tools with different workflows based on how they apply to document elements; learning the correct sequence ensures frustration-free PDF editing.
Adobe Acrobat processes continuous area selections (like highlights) differently from point-specific insertions. The Highlight tool is a continuous state tool, meaning you can activate it once and drag over multiple text segments. The Insert Text tool, however, requires a specific insertion point, so Acrobat's design mandates defining that precise location first before calling the function.
Click the 'Highlight text' icon in the Comment toolbar first, then click and drag over the text you want to highlight. You can continue highlighting multiple sections until you select another tool or press Esc.
Using your cursor, click exactly in the document text where you want to add an annotation. Once the blinking cursor is active at that insertion point, click the 'Insert text at cursor' icon in the Comment toolbar to open the text entry box.
Alternatively, right-click the specific cursor location or the highlighted text and use the right-click context menu to select 'Add Note to Replace Text' or 'Insert Text at Cursor'.

Edit and Annotate PDFs Effortlessly with WPS Office
If strict tool selection orders in other PDF software slow down your workflow, try the WPS PDF editor. WPS Office offers an intuitive, user-friendly interface for adding highlights, inserting text, and commenting on PDFs without confusing operational restrictions.
- 1. Open your PDF in WPS Office: Launch WPS Office and open your PDF document. Navigate to the 'Comment' tab located on the top ribbon.
- 2. Highlight Text Easily: Click the 'Highlight' button. Because of its flexible design, you can either select text first and click Highlight, or select the tool first and drag over the text.
- 3. Insert Text with an Intuitive Workflow: Click the 'Text Box' or 'Insert Text' tool directly from the ribbon, then click anywhere on the page document to immediately start typing your annotations.

Frequently Asked Questions
Can I change how the Insert Text tool behaves in Adobe Acrobat?
No, the requirement to place the cursor before selecting the Insert Text tool is hardcoded into Adobe Acrobat's interface design. It is not currently adjustable in the settings.
Why does the Highlight tool stay active after I use it once?
The Highlight tool is designed as a continuous-use tool so users can mark up multiple paragraphs quickly. To stop highlighting, simply press the 'Esc' key on your keyboard or select the default Selection tool (arrow icon) from the toolbar.
Are there keyboard shortcuts for Acrobat commenting tools?
Yes, standard shortcuts are available depending on your Acrobat version and workspace settings. Typically, pressing 'U' activates the Highlight tool. For inserting text, relying on placing the cursor and using the right-click menu is often the fastest workflow.
