Expression language guide key

Use the following key when referencing the expression language guide:

• Headings represent expression objects. All elements listed below a heading are attributes (that you can retrieve from the object) or methods (that you can call on the object). Many of the attributes and methods return other objects--look up those object types in this guide to determine how to continue your expression.
• Italic text at the beginning of a description represents the return value type. Some return values include a number in square brackets--this number specifies the dimension of the returned property or array. If a specific dimension is not included, the dimension of the returned array depends on the dimension of the input.
• Bold text represents the expression language element to type in your expression.
• (Bold Italic) text inside parentheses represents the argument(s), which is the type of information that you need to add inside the parentheses. If an argument contains an equal sign (=) and a value (such as t=time or width =.2), the argument uses the included default value if you don't specify a different value.
• {Italic and Roman} text inside curly brackets represents the argument description. Some argument descriptions include a number in square brackets--this number indicates the dimension of the expected property or array. If a specific dimension is not included, any dimension will work.
• Roman text is a description and possibly an example of the element.
