.SM

Prints all text following in the normal point size (that is, the value of the
PS register).
\*[{]

.IP [marker [width]]
[Macro]
The marker is usually a bullet glyph (\[bu]) for unordered lists, a number
(or auto-incrementing number register) for numbered lists, or a word or
phrase for indented (glossary-style) lists.
The width specifies the indentation for the body of each list item; its
default unit is ‘n’. Once specified, the indentation remains the same for
all list items in the document until specified again.
The PORPHANS register (see Section 4.3.3 [ms Document Control Registers],
page 33) operates in conjunction with the IP macro, to inhibit the
printing of orphaned list markers at the bottom of any page.
The following is an example of a bulleted list.
