> UPPERCASE | Indicates keys or key combinations that you can use. For example, press the ENTER key.
> `monospace` | Indicates syntax examples, values that you specify, or results that you receive.
> `monospaced italics` | Indicates names that are placeholders for values you specify; for example, `filename`.
> forward slash / | Separates menus and their associated commands. For example, Select File / Copy means to select Copy from the File menu.
> vertical rule | | Indicates an OR separator to delineate items.
> brackets [ ] | Indicates optional items. For example, in the following statement: SELECT [DISTINCT], DISTINCT is an optional keyword.
> braces { } | Indicates that you must select one item. For example, {yes | no} means you must specify either yes or no.
> ellipsis . . . | Indicates that the immediately preceding item can be repeated any number of times in succession. An ellipsis following a closing bracket indicates that all information in that unit can be repeated.
