Ruler type feature that displays or highlights one row at a time. Similar to using a ruler on a piece of paper that a typist uses to type data from that one line.

When I have rows of data that I need to use in another program, it is difficult viewing the information on a screen and typing that information into another program, and it is also difficult to keep track of placement in the pdf.

A ruler that highlights one row and blocks out others, that can be moved down the screen as rows are used, would be great to have.
