In Reader, complete commenting tools are available only in PDFs that have commenting enabled. PDFs in a review workflow typically include commenting rights.
You can use text edit comments in a PDF to indicate where text should be edited in the source file. Text edit comments do not change the actual text in the PDF. Instead, they indicate which text should be deleted, inserted, or replaced in the source file from which the PDF was created.
Acrobat offers two basic methods to add text edit annotations: pre-select and post-select.
Pre-select or Text Correction Markup tool
Use the Select tool , or the Text Correction Markup tool and then right-click (Windows) or Control-click (Mac OS) on the selected text to open a menu of text editing options. After marking the text, you can also click on a text edit tool.
Click the text edit tool and then select the text.
In Acrobat for Windows, you can export text edits directly to the Microsoft Word document that the PDF is based on to revise the source document. To use this feature, you must use PDFMaker in Word to create the PDF. Before you export your text edits, make sure that insertion comments use the exact text, including spaces and paragraph returns, that you want to add. If you add extra instructional words (such as “Add the following:”), these words will have to be deleted manually from the Word document.
In Acrobat Pro on Windows, you can export text edit comments directly to an Autodesk AutoCAD document that the PDF is based on to incorporate your edits. To use this feature, you must use PDFMaker in AutoCAD to create the PDF.
Type the text you want to insert.
To indicate that a new paragraph should be added, press Enter, and then close the pop-up note without adding text. The paragraph insertion caret appears.
To indicate that a space should be added, press the spacebar, and then close the pop-up note without adding text. The space insertion caret appears.
You can also indicate text edits by using the Select tool to select text, right-click the selected text, and then choose a text edit annotation.
If markup comments are stacked, delete the comments in the Comments list: Choose Comment > Comments List, select the comment, and press Delete.
In Reader only Sticky Note and Highlight tools are available. Other commenting tools are available only in PDFs that have commenting enabled. PDFs in a review workflow typically include commenting rights.
You can use the Highlight Text tool, Strikethrough Text tool, and the Underline Text tool to add comments by themselves or in conjunction with notes.
You can add a highlight with a note or you can cross out text or underline text by selecting the text using the Select tool, right-clicking, and then choosing that option from the menu that appears. However, if you’re marking up a lot of text, the specialized tools are faster and easier to use.
Choose Tools > Comment, and select the Highlight Text tool , the Strikethrough Text tool , or the Underline Text tool .
If you want to apply more than one comment using the Strikeout Text tool or the Underline Text tool, choose Keep Tool Selected from the Options menu after you select the tool. The Highlight Text tool stays selected after you make the first comment.
Note that you can also change the color of the highlighted text. Right-click (Windows) or Control-click (Mac OS) on the highlighted text and click Properties to open the Highlight Properties dialog box, which will allow you to change the color.
In case if you need to delete the highlight on the text (without deleting the text), right-click (Windows) or Control-click (Mac OS) on the highlighted text and click Delete.
