format that plays in Windows and Mac OS.

compatible. The specified movie must be embedded in a PDF document.

Read An Article
Follows an article thread in the active document or in another PDF document.
Reset A Form
Clears previously entered data in a form. You can control the fields that are reset with the Select Fields
dialog box.
Run A JavaScript
Runs the specified JavaScript.
Set Layer Visibility
Determines which layer settings are active. Before you add this action, specify the appropriate
layer settings.
Show/Hide A Field
Toggles between showing and hiding a field in a PDF document. This option is especially useful
in form fields. For example, if you want an object to pop up whenever the pointer is over a button, you can set an
action that shows a field on the Mouse Enter trigger and hides a field on Mouse Exit.
Submit A Form
Sends the form data to the specified URL.
Trigger types
Triggers determine how actions are activated in media clips, pages, and form fields. For example, you can specify a
movie or sound clip to play when a page is opened or closed. The available options depend on the specified page
element.
You can use the following triggers for media clips and form fields (not links or bookmarks):
Mouse Up
When the mouse button is released after a click. This is the most common button trigger, because it gives
the user one last chance to drag the pointer off the button and not activate the action.
Page Visible (media clips only)
When the page containing the media clip is visible, regardless of whether it is the
current page. It’s possible for a page to be visible without being the current page, such as when a continuous page
layout displays pages side-by-side.
Page Invisible (media clips only)
When the page containing the media clip is moved out of view.
Page Enter (media clips only)
When the page containing the media clip becomes the current page.
Page Exit (media clips only)
When a user leaves the page that contains the media clip.
Mouse Down
When the mouse button is clicked (without being released). In most cases, Mouse Up is the preferred
trigger.
Mouse Enter
When the pointer enters the field or play area.
Mouse Exit
When the pointer exits the field or play area.
On Receive Focus (media clips only)
When the link area receives focus, either through a mouse action or tabbing.
On Lose Focus (media clips only)
When the focus moves to a different link area.

About JavaScript in Acrobat
The JavaScript language was developed by Netscape Communications as a means to create interactive web pages
more easily. Adobe has enhanced JavaScript so that you can easily integrate this level of interactivity into your PDF
documents.
You can invoke JavaScript code using actions associated with bookmarks, links, and pages. The Set Document
Actions command lets you create document-level JavaScript actions that apply to the entire document. For example,
selecting Document Did Save runs the JavaScript after a document is saved.
You can also use JavaScript with PDF forms and batch sequences. The most common uses for JavaScript in forms are
formatting data, calculating data, validating data, and assigning an action. Field-level scripts are associated with a
specific form field or fields, such as a button.This type of script is executed when an event occurs, such as a Mouse
Up action.
To learn how to create JavaScript scripts, download the JavaScript manuals from the Adobe website. Developing
Acrobat® Applications Using JavaScript™ contains background information and tutorials, and the JavaScript™ for
Acrobat® API Reference contains detailed reference information. These and other JavaScript resources are located on
the Adobe website.
Converted web pages
Links and bookmarks in web pages
You can work with a PDF document created from web pages the same way you work with any other PDF. Depending
on how you configured Acrobat, clicking a link on a converted web page adds the page for that link to the end of the
PDF, if it isn’t already included.
Note:
Remember that one web page can become multiple PDF pages. A web page is a single topic (or URL) from a website
and is often one continuous HTML page. When you convert a web page to PDF, it may be divided into multiple
standard-size PDF pages.
When you first create a PDF from web pages, tagged bookmarks are generated if Create Bookmarks is selected in the
Web Page Conversion Settings dialog box. A standard (untagged) bookmark representing the web server appears at
the top of the Bookmarks tab. Under that bookmark is a tagged bookmark for each web page downloaded; the tagged
bookmark’s name comes from the page’s HTML title or the URL, if no title is present. Tagged web bookmarks are
initially all at the same level, but you can rearrange them and nest them in family groups to help keep track of the
hierarchy of material on the web pages.
If Create PDF Tags is selected when you create a PDF from web pages, structure information that corresponds to the
HTML structure of the original pages is stored in the PDF. You can use this information to add tagged bookmarks
to the file for paragraphs and other items that have HTML elements.

Refresh converted web pages
You can refresh web pages in a PDF to retrieve the most up-to-date version from the website. When you refresh, you
download the entire website or link again and build a new PDF. The resulting new PDF lists any pages where compo
nents have changed, including text, web links, embedded filenames, and formatting. New pages are downloaded if
they have been added to the site. The changed pages are listed as bookmarks in the Bookmarks panel under a
bookmark labeled New And Changed Pages.
You can refresh web pages only if Save Refresh Commands was selected when the pages were first downloaded.

Define articles
You create an article by defining a seriesof boxes around the content in the order in which you want the content read.
The navigational path you define for an article is known as the article thread. You create a thread connecting the
various boxes, unifying them into a continuous text flow.

Optimizing
PDF Optimizer
PDF Optimizer provides many settings for reducing the size of PDF files. Some of the PDF Optimizer settings are
comparable to the settings that are available when you create a PDF file using Distiller. Whether you use all of these
settings or only a few depends on how you intend to use the files and on the essential properties a file must have. In
most cases, the default settings are appropriate for maximum efficiency—saving space by removing embedded fonts,
compressing images, and removing items from the file that are no longer needed.
Before you optimize a file, it’s a good idea to audit the file’s space usage. The space audit results may give you ideas
about where best to reduce file size. You can also reduce the size of your PDF by using the Reduce File Size command.
Important:
Some methods of compression may make images unusable in a print production workflow. You should
experiment with various settings before making changes that can’t be discarded.

Open the PDF Optimizer
❖
To open the PDF Optimizer dialog box, do one of the following:
• Choose Advanced > PDF Optimizer.
• Choose Advanced > Print Production > PDF Optimizer.
• Click the PDF Optimizer icon
in the Print Production toolbar.
Note:
PDF Optimizer isn’t available when Reflow is selected in the View menu.
Audit the space usage of a PDF
Auditing the space usage gives you a report of the total number of bytes used for specific document elements,
including fonts, images, bookmarks, forms, named destinations, and comments, as well as the total file size. The
results are reported both in bytes and as a percentage of the total file size.
1 Choose Advanced > PDF Optimizer.
2 Click the Audit Space Usage button at the top of the dialog box.
