Working with hanging characters
Hanging character sets handle both hanging punctuation and margin alignment. Margin alignment lets you hang characters partially outside the margin to create visually uniform text alignment along the margin. Hanging punctuation lets you hang punctuation characters fully outside the margin so that the text is flush against either a uniform margin at the beginning of a line of text (leading) or against a uniform margin at the end of a line of text (trailing). For example, the quotation mark in the first sample text below is hanging outside the leading margin, which allows the first character in the first line of text to align evenly with the rows of text below it. The quotation mark in the second sample text below is hanging outside the trailing margin.
The opening quotation mark in this sample text is a leading hanging character
The closing quotation mark in this sample text is a trailing hanging character
You can create custom hanging character classes and hanging character sets, or you can use the default classes and sets that come with the software. A hanging character class is a group of characters that should always hang outside the margin or indent inside the margin by the same percentage. A hanging character set is a group of hanging character classes. You can use a hanging character set to apply one or several hanging character classes to paragraphs.
To view, create, edit, duplicate, and delete hanging character sets and classes, use the Hanging Characters dialog box (Edit > Hanging Characters).
The Hanging Characters dialog box
Hanging character sets are preceded by a 
icon. Hanging character classes are preceded by a 
icon.
If you select a hanging character set in the center pane of the dialog box, the lower pane displays the hanging character classes that belong to that set. If you select a class in the center pane of the dialog box, the lower pane displays the sets to which the selected class belongs and the attributes of the selected class.
