Selecting data - especially something as small as a dot - can be difficult in a
PDFfile. To make sure that a Condition step checks for certain data: Type the value
in the right operand (in the Step properties pane).Move or resize the selection
rectangle in the data.Click the Use selection button in the left operand (in the
Step properties pane).When the Condition evaluates to true, the value is found in
the selected region.
In the Data Viewer, you will see a green check mark in the left margin next to each
included line and an X for other lines.
