Indexes and cross-references
Note:
When indexing a document, pay attention to whether index markers are placed inside or outside conditional text.
Keep in mind that index markers in hidden conditional text are not included in the generated index.
If you create a cross-reference to conditional text, make sure that the source text has the same condition. For example, if you add a cross-
reference in a “Windows” paragraph and the text anchor appears in a “Mac” condition, the cross-reference is unresolved when the “Mac” condition
is hidden. “HT” appears next to the cross-reference in the Hyperlinks panel.
If you create a cross-reference to a paragraph in which some text is conditional and then change the visibility settings of that condition, update the
cross-reference.
Create conditions
Conditions you create are saved in the current document. If no documents are open when you create a condition, that condition appears in all new
documents you create.
You can make conditional text easy to identify by specifying condition indicators, such as wavy red underlines.
1. Choose Window > Type & Tables > Conditional Text to display the Conditional Text panel.
2. Choose New Condition from the Conditional Text panel menu, and type a name for the condition.
3. In the Indicator group, specify the appearance of the indicator to which the condition is applied.
By default, indicators (such as wavy red lines) are set to appear in the document but not be printed or output. You can choose an option
from the Indicators menu in the Conditional Text panel to hide indicators or to print and output them, which can be useful for review
purposes.
4. Click OK.
Apply conditions to text
You can apply multiple conditions to the same text. By default, condition indicators identify conditional text. However, if indicators are hidden, you
can use the Conditional Text panel to determine which conditions have been applied to the current text. A solid check mark indicates the condition
is applied to the current text. A dim check mark indicates that the condition is applied only to part of the selection.
1. Select the text to which you want to apply the condition.
2. In the Conditional Text panel (Windows > Type & Tables > Conditional Text), do any of the following:
To apply a condition, click the condition, or click the box next to the condition name.
To apply a condition and remove other conditions applied to the text, Alt-click (Windows) or Option-click (Mac OS) a condition.
To remove a condition, click the box next to the condition name to remove the check mark. Or, click [Unconditional] to remove all
conditions from the selected text.
You cannot apply keyboard shortcuts to specific conditions. However, you can apply conditions using Quick Apply.
Show or hide conditions
When you hide a condition, all text to which that condition is applied is hidden. Hiding conditions often causes the page numbering to change in a
document or book. You can use the Smart Text Reflow feature to add and remove pages automatically as you hide and show conditions.
Hidden conditional text is generally ignored in the document. For example, hidden text is not printed or exported, index markers in hidden
conditional text are not included in a generated index, and hidden conditional text is not included when searching or spell-checking text.
When you hide a condition, the hidden text is stored in a hidden condition symbol . If you select text that contains a hidden condition symbol and
