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). Y ou 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.
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.
Figure 7-3 on page 171 shows an example of a box that is intended to capture the text 
string Content. Y ou can see that the box is much larger than the text string, and it 
overlaps onto text that we do not want to collect. However, notice the Add a Trigger box 
that is displayed; only the string Content is shown in the Value entry field, which means 
that only the string Content is fully encapsulated in the box. Overlapping other text 
might seem like an unnecessary precaution. However, when we are capturing data with 
the PDF graphical indexer, it is an excellent way to ensure that we encapsulated all of 
the text string that we must capture. 
Note: To create trigger values in hexadecimal, select the Output Hexadecimal 
Strings check box in the Indexer Properties window before you define a trigger.
Important: Size the box that you created around the text string, which you are trying 
to collect, as large as possible to ensure that the field is collected at load time.
