The Text lines panel (Panels menu, Show text lines panel) lists the text lines that the OCR found on the current page, with the document and page number and the text of each line. Click a line to highlight its rectangle in the viewer.
It is useful to check what the OCR really read before writing an Intelli-Tag or a regular expression, to find a value that does not appear where expected, and to see how the page layout was segmented (the same lines and blocks that the View layout option of the Indexing tab draws over the image).
