How do I add a line from the end of a sentence to the edge of the paper in Pages?

Solution 1:

The easy way to do this is to select the first line - change the text style to be underline and add tabs after the “e” in experience.

This way, the underline goes as far right as you please.

Adding a horizontal line is fine as well if you can accept a line break under the heading and before the list starts.

Both of these work on iOS pages, web app pages as well.
