About Accessibility

1. In Doc-To-Help, open the Home ribbon, and at the bottom of the Target group click . The Help Targets dialog opens.
2. On the left, choose your NetHelp project.
3. In the Advanced section, go to the Accessibility mode field and choose Section 508.

The following features are enabled when the Accessibility mode is set to Section 508:

• All links generated by Doc-To-Help have title strings (indicating the link type) and appear as tooltips that are read by accessibility devices. The default title strings are: link, popup, expanding text, and drop-down text. These strings can be changed.
• Popup links become jump links to allow easier accessibility. For the same reason, margin notes and glossary term links, which usually appear as pop-up windows in normal mode, are not shown as popups but as normal HTML pages in the main frame.
• Inline popup text is shown as inline (or expanding) text rather appearing in a popup box.
• When a user clicks a group or keyword link or a keyword in the index that has multiple destination topics, the destinations are shown in the main frame as a normal HTML page. By default, the heading of this page is "N Topics Found" where "N" is the number of topics associated with the group or keyword. The page heading can be changed.

• A “Skip to main content” option becomes available to users when they open a topic and press TAB. After users encounter this option, they can press ENTER to bypass the navigation.

  Example  

  You have a NetHelp target that is using “Normal” mode.

  

  A user who is visually impaired opens your generated output and presses the TAB key. The cursor moves to the Search field.

  

  The user continues to press the TAB key, and the focus moves through each navigation element. In the following example, the user must press TAB 26 more times before focus finally lands in the topic content.

  

  Therefore, you edit the target and choose the Section 508 mode.

  

  The same user opens the generated output and presses the TAB key. This time, the user is told that she can skip to the main content.

  

  After pressing ENTER on the keyboard, the user’s experience is that focus moves immediately to the topic content.

  

The following features are enabled, regardless of the Accessibility mode chosen:

• All links and buttons are accessible from the keyboard using the TAB key.

• Each frame of a NetHelp theme has a title string that can be read by accessibility devices. By default, the title strings match the frame titles. The default strings are: Topic navigation, Top topic navigation, Bottom topic navigation, Navigation panes, Topic text, Index pane, Index list, Search pane, and Search result list. These strings can be changed.

In order for your project to be Section 508 compliant, all images in your source documents must have alternative text, which is a description that can be read by accessibility devices. Alternate text can be added to multimedia (e.g., videos) from the Insert Multimedia dialog.

To Add Alternate Text to an Image

1. Right-click on the image and from the menu, select Format Picture. The Format Picture dialog opens.
2. Click the Alt Text tab, and in the Alternative text box enter the text.
3. Click OK.

Doc-To-Help will provide warnings in the build log if any images without alternative text are found in the Word source documents of your project. These warnings can be ignored if certain images do not need alternative text and will not interfere with accessibility. Doc-To-Help inserts an empty alternative text tag in the NetHelp target if text is not provided.

Tables must have a caption specified in order to be Section 508 compliant.

Although Word displays the caption as normal text with no special formatting, Doc-To-Help places the <caption> tag inside the <table> tag when NetHelp is generated.

The summary describes the table’s purpose and usually provides more detail than the caption. It is not displayed in the target, but is read by accessibility devices. Although Word does not have a feature for specifying a table summary, this can be done by inserting a comment within a table. Doc-To-Help will interpret the comment as the table’s summary.

In Word source documents do the following:

How to Add a Caption to a Table

1. Select the entire table and right-click.

2. From the menu, select Insert Caption. The Caption dialog opens.

3. Click the New Label button. Enter the caption and click OK.

4. Click OK to close the Caption dialog.

How to Add a Comment (Summary) to a Table

1. Select the entire table or place your cursor within a cell.

2. Click the Review tab, and then click the New Comment button.

3. Enter the comment.

Doc-To-Help will provide warnings in the build log if any tables without captions and summaries are found in the Word source documents of your project. These warnings can be ignored if certain tables do not need captions and summaries and will not interfere with accessibility. Doc-To-Help inserts an empty caption in the target if text is not provided.

If you are using a custom theme, you can edit the text used for this option.

1. On the Target ribbon, click the Target Theme drop-down and select the custom theme you wish to edit (not a predefined theme).
2. On the Target ribbon, click the Designer button.

3. On the right side of the Theme Designer, click the drop-down and select accessibility.

   

4. Scroll down and in the right column, edit the Skip to main content text.

   

5. Click OK.
