// We can use the section's PageSetup object to display numbers to the left of the section's text lines.
// This is the same behavior as a List object,
// but it covers the entire section and does not modify the text in any way.
// Our section will restart the numbering on each new page from 1 and display the number,
// if it is a multiple of 3, at 50pt to the left of the line.

// The line counter will skip any paragraph with the "SuppressLineNumbers" flag set to "true".
// This paragraph is on the 15th line, which is a multiple of 3, and thus would normally display a line number.
// The section's line counter will also ignore this line, treat the next line as the 15th,
// and continue the count from that point onward.
