Annotate Text with Acrobat CS5 Text Edits Tool
You can easily annotate text in an Adobe Acrobat Creative Suite 5 PDF file by using the Comment & Markup toolbar, which you can access by clicking the Comment option in the Tasks toolbar. You can then choose Show the Comment & Markup Tools.
You can also access the Comment & Markup toolbar by choosing View→ Toolbars→Comment & Markup.
The Text Edits tool is actually six separate text commenting tools. Use these tools to replace selected text, highlight selected text, add a note to selected text, insert text at cursor, underline selected text, and cross out text for deletion.
To use the Text Edits tool, follow these steps:
Choose the Text Edits tool and drag to select text that requires a change or comment.
Click the arrow to the right of the Text Edits tool to access the drop-down list containing your six choices.
Choose an option from the list of available editing choices:
Replace Selected Text: Replaces the selected text.
Highlight Selected Text: Highlights the selected text.
Add a Note to Selected Text: Allows you to add a note to the selected text.
Insert Text at Cursor: Places a cursor at the end of the selected text.
Underline Selected Text: Underlines the selected text.
Cross Out Text for Deletion: Crosses out the selected text.
Your selected text changes, depending on what you choose from the list.
After selecting the text that requires a comment, you can press the Delete or Backspace key to indicate a text edit to remove the text. Similarly, you can start to type, and Acrobat will create an insertion point. Also, if you right-click (Windows) or Control-click (Mac) after selecting the text, you can select the type of edit or comment you want to insert from the contextual menu.
