Adobe Acrobat 7 Professional - Manual (Page 468)

Editing images and objects
Using the TouchUp Object tool, you can select an image or object in a PDF document and
move it to a new location, edit it using the TouchUp Object tool features, or take it into
Adobe Photoshop, Adobe Illustrator, or another application directly from the PDF
document, and edit it. Once you complete the edit, you can place the image or object
directly back in the PDF document if you are using an external application, and view the
newly edited image or object in its original context. To take full advantage of this tool,
you should have prior experience using the external editing applications accessed by the
TouchUp Object tool.
If you edit a text box, the entire text box is selected. The TouchUp Object tool cannot
select individual characters that are part of larger text blocks. You need to use the
TouchUp Text tool to edit individual characters and words. (See
Editing text with the
TouchUp Text tool .)
Note: Comments--even though they have a graphic appearance--are not considered page
elements and therefore cannot be selected or manipulated using the TouchUp tools.
