Options[expr]

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

Options
gives a list of the settings for the options .
  • Many built-in functions allow you to give additional arguments that specify options with rules of the form .
  • 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 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.
