or to portions of a user interface, such as the Back button or the Options menu.

literally when programming, including keywords, data types,
constants, method names, variables, class names, and interface names.
- Constant Width Italic
Used for the names of function arguments and generally as a
placeholder to indicate an item that should be replaced with an
actual value in your program. Sometimes used to refer to a conceptual
section or line of code as in statement.

without a lot of distracting line breaks. This font is also used for
code entities in the descriptions in the quick reference section.

Used for highlighting class, method, field, property, and constructor
names in the quick reference section, which makes it easier to scan
the class synopses.
