The style of text, known as typography, helps you identify special words used in this manual. These words frequently show in specifications of syntax and examples of source code.

Examples	Information
`ByRef, In, Rem, UInt32`	Language keywords are shown with an initial upper-case letter, with the format shown in the example.
`ANSI, CDECL, DONE`	Non-reserved keywords are shown with all upper-case letters, with the format shown in the example.
`condition, #object, argument_list`	Information that you supply is shown with an initial lower-case letter, with the format shown in the example.
`name [ = value ]`	In syntax specifications, items in brackets are optional. You can use the item, or ignore it.
`{ While \| Until }`	In syntax specifications, braces and vertical bars show a necessary decision between two or more alternatives. You must use one, and only one, of the items.
`[ In \| Out ]`	In syntax specifications, brackets and vertical bars show an optional decision between two or more alternatives. You can use one of the items, or none of the items.
`parameter [ , parameter ]…`	In syntax specifications, three dots show that the item before can be used as many times as necessary. In code examples, three dots are used where code was removed to make the example easier to read.
«`+`»	In paragraph text, items can be between a pair of angular quotation symbols. You see this when an item is adjacent to a symbol that is not part of that item. One such symbol is a period at the end of a sentence.
`ESC`, `ENTER`	Key names and key sequences on the keyboard are shown with all upper-case letters.
`CTRL+S`	When plus symbols (+) are written between key names, you must push and hold one key while you push the other. For example, `CTRL+S` tells you to push and hold `CTRL` while you push `S`.
