4.6.5.7 Indented regions

You can indent a region of text while otherwise formatting it normally. Such indented regions can be nested; change \n[PI] before each call to vary the amount of inset.

Macro: .RS

Begin a region where headings, paragraphs, and displays are indented (further) by the amount stored in the PI register.

Macro: .RE

End the (next) most recent indented region.

This feature enables you to easily line up text under hanging and indented paragraphs. For example, you may wish to structure lists hierarchically.
