gives the list of default options assigned to a symbol.
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.
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 namei.
  • 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.
  • Options always returns a list of transformation rules for option names.
  • 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.
  • If you ask for Options[NotebookObject[...], name] the kernel will send a request to the front end to find the result.
  • Explicit values are found for options associated with cells even if these options are only set at the style, notebook or global level.
