text: 6. Press F1 to open the main help topic for the report window. 
  
  The main help topic contains general information about the report window and links to 
  other topics that describe how to add triggers, fields, and indexes. For example, to get help 
  to define a trigger, click**Adding a trigger (PDF)**. You can also use the context help tool to 
  display information about the icons on the toolbar. 
  
  7. Close any open help topics and return to the report window. 
  
  8. To define a trigger, complete the following steps: 
  
  a. Find a text string that uniquely identifies the beginning of a document, for example, 
  Account Number, Invoice Number, Customer Name. 
  
  **Note:**To create trigger values in hexadecimal, select the**Output Hexadecimal**
  **Strings**check box in the Indexer Properties window before you define a trigger. 
  
  b. By using the mouse, draw a box around the text string. Start just outside of the 
  
  upper-left corner of the string. Click and then drag the mouse toward the lower-right 
  corner of the string. As you drag the mouse, the graphical indexer uses a dotted line to 
  draw a box. After you enclose the text string inside a box, release the mouse. The 
  graphical indexer highlights the text string inside the box. If the string is not highlighted, 
  try again and increase the box’s size.
