When you click the pop-up menu button on the Indicate Text Edits tool, it displays options for marking up edited text selections. You normally use this group of commands in conjunction with the Indicate Text Edits tool to perform various markups on selected text in PDF document you’re reviewing for the benefit of other review participants. These self-explanatory options include Insert Text at Cursor, Replace Selected Text, Highlight Selected Text, Add Note to Selected Text, Cross Out Text for Deletion, and Highlight Selected Text, among others. When you click the pop-up menu button on the Stamp tool, it displays all the options for using the electronic rubber stamp feature in Acrobat 6.
When you click the pop-up menu button on the Highlight tool, it displays different highlighting tools — Cross-Out Text tool and the Underline Text tool, in addition to the standard Highlighter tool. You usually use this group of tools to draw attention to text in the PDF document you’re reviewing that needs some type of editing (normally deletion, when you use the Cross-Out Text tool) or emphasizing (when you use the Underline Text tool). See the “Hitting the highlights” section, later in this chapter, for details. Note that Acrobat saves all notations that you add with Commenting and Advanced Commenting tools on a distinct and invisible top layer of the PDF document, keeping them separate from the PDF document text and graphics underneath. This makes it possible for you to import comments from other reviewers and add them to the PDF document, as well as to summarize all comments made in the document and export them as a separate file.
