Built-in Mathematica Symbol

Options

Options[symbol]
gives the list of default options assigned to a symbol.

Options[expr]
gives the options explicitly specified in a particular expression such as a graphics object.

Options[stream] or Options["sname"]
gives options associated with a particular stream.

Options[object]
gives options associated with an external object such as a NotebookObject.

Options[obj, name]
gives the setting for the option name.

Options[obj, {name₁, name₂, ...}]
gives a list of the settings for the options name_i.

Many built-in functions allow you to give additional arguments that specify options with rules of the form name->value.

Options[f] gives the list of rules to be used for the options associated with a function f if no explicit rules are given when the function is called.

You can assign a value to Options[symbol] to redefine all the default option settings for a function.

SetOptions[symbol, name->value] can be used to specify individual default options.

You can use Options on InputStream and OutputStream objects. If there is only one stream with a particular name, you can give the name as a string as the argument of Options.
