Use Line Check to find widows, orphans, loosely justified lines, lines that end with a hyphen, and text box overflow. Line Check moves through a document, highlighting the questionable lines, much as the Spell Check function highlights questionable words.
Specify search criteria
1. Choose Search Criteria from the Line Check submenu (Utilities menu) to open the Search Criteria dialogue box. Check the categories of undesirable typography you want to search for:
 
• Loose Justification is a justified line containing word or character spaces that exceed the maximum word and character space values in the H&J specifications applied to its paragraph.
• An Auto Hyphenated line ends with a hyphen placed by the automatic hyphenation function.
• A Manual Hyphenated line ends with a hyphen typed in by a user.
• A Widow is the last line of a paragraph, less than a full measure wide, that falls at the top of the following column or page.
• An Orphan is the first line of a paragraph that falls at the bottom of a column or page.
• Text Box Overflow occurs when text cannot be displayed within its text box. This condition is represented by an overflow symbol in the lower right corner of a text box. There must be at least one line of visible text in a text box for Line Check to find overflow. Also, text must cause the overflow; invisible characters such as paragraph returns and enter characters that generate overflow will not be found.
2. Click the Count to get a count of all typographically undesirable lines. The count for each category appears on the right side of the box.
3. Click OK.
NOTE: The Line Check search criteria you specify become application defaults, until you change them. The settings are not document specific.
Implement a search
1. To search the entire document, choose First Line (Utilities menu, Line Check). To search from the location of the Text Insertion bar to the end of the document, place the Text Insertion bar where you want to start the search and choose Next Line (Utilities menu, Line Check) or press Cmd - ;.
 
2. The first typographically undesirable line is highlighted. You can interrupt the search at any time to fix a line. Press Cmd - ; to continue the search.
