Page thumbnails are miniature previews of the pages in a document. You can use page thumbnails to jump quickly to a selected page or to adjust the view of the page. When you move, copy, or delete a page thumbnail, you move, copy, or delete the corresponding page.
If you do not see page thumbnails in the navigation pane, try using F4 to open the navigation pane. Or choose View > Show/Hide > Navigation Panes > Page Thumbnails.
Page thumbnails increase file size, so Acrobat does not create them automatically.
Acrobat no longer supports embedding and unembedding page thumbnails. However, Acrobat Distiller® provides an alternate method of embedding page thumbnails.
Page thumbnails appear in the navigation pane. This process may require several seconds, particularly in larger documents. The drawing of page thumbnails may pause if you interact with the application during this process.
In the Page Thumbnails panel, you can set the order in which a user tabs through form fields, links, and comments for each page.
Use Row Order
Moves through rows from left to right, or right to left for pages with a right-to-left binding.
Use Column Order
Moves through columns from left to right and from top to bottom, or right to left for pages with a right-to-left binding.
Use Document Structure
Moves in the order specified by the authoring application.
For structured documents—PDFs that were created from desktop publishing applications or that contain tags—it’s best to select the Use Document Structure option to match the intention of the authoring application.
If the document was created in an earlier version of Acrobat, the tab order is Unspecified by default. With this setting, form fields are tabbed through first, followed by links and then comments ordered by row.
A bookmark is a type of link with representative text in the Bookmarks panel in the navigation pane. Each bookmark goes to a different view or page in the document. Bookmarks are generated automatically during PDF creation from the table-of-contents entries of documents created by most desktop publishing programs. These bookmarks are often tagged and can be used to make edits in the PDF.
Initially, a bookmark displays the page that was in view when the bookmark was created, which is the bookmark’s destination. In Acrobat, you can set bookmark destinations as you create each bookmark. However, it is sometimes easier to create a group of bookmarks, and then set the destinations later.
In Acrobat, you can use bookmarks to mark a place in the PDF to which you want to return, or to jump to a destination in the PDF, another document, or a web page. Bookmarks can also perform actions, such as executing a menu item or submitting a form.
An Acrobat user can add bookmarks to a document only if the security settings allow it.
To bookmark a single image, click in the image or drag a rectangle around the image.
To bookmark a portion of an image, drag a rectangle around the portion.
To bookmark text, drag to select it. The selected text becomes the label of the new bookmark. You can edit the label.
Choose Tools > Edit PDF > More > Add Bookmark.
In Reader, you can make bookmarks easier to read by changing their text appearance.
In Acrobat, you can change a bookmark’s attributes at any time.
All the text of long bookmarks shows regardless of the width of the navigation pane. (This option is on when checked, and off when not checked.)
You can change the appearance of a bookmark to draw attention to it.
After you have
defined a bookmark’s appearance, you can reuse the appearance settings.
To do this, select the bookmark and from the options menu , choose
Use Current Appearance As New Default.
The Set Bookmark Destination option is context sensitive. It appears only when you have an existing bookmark selected.
In the Bookmarks panel, click the Options menu .
Click Set Default Bookmark Zoom Level, and choose the desired zoom level. By default, the Inherit Zoom option is selected.
When you adjust the zoom level of multiple bookmarks, the destination page number for the selected bookmarks is retained by default.
To change the destination page number of the bookmarks, do the following:
Select two or more bookmarks that you want to change the zoom level.
Right-click the bookmark and then choose Properties.
In the Bookmark Properties dialog, click Actions.
Choose Go To A Page In This Document and then click Edit.
Uncheck the option Keep Page Number Unchanged.
Deleting a bookmark deletes any bookmarks that are subordinate to it. Deleting a bookmark does not delete any document text.
You can nest a list of bookmarks to show a relationship between topics. Nesting creates a parent/child relationship. You can expand and collapse this hierarchical list as desired.
The bookmark is nested; however, the actual page remains in its original location in the document.
Drag the icon or icons, positioning the arrow directly under the label of the parent bookmark.
Choose Cut from the options menu , select the parent bookmark, and then choose Paste Under Selected Bookmark from the options menu.
Tagged bookmarks give you greater control over page content than do regular bookmarks. Because tagged bookmarks use the underlying structural information of the document elements (for example, heading levels, paragraphs, table titles), you can use them to edit the document, such as rearranging their corresponding pages in the PDF or deleting pages. If you move or delete a parent tagged bookmark, its children tagged bookmarks are moved or deleted along with it.
Many desktop publishing applications, such as Adobe InDesign® and Microsoft Word, create structured documents. When you convert these documents to PDF, the structure is converted to tags, which support the addition of tagged bookmarks. Converted web pages typically include tagged bookmarks.
If your document doesn’t include tags, you can always add them in Acrobat.
The tagged bookmarks are
nested under a new, untitled bookmark.
