InputNotebook

InputNotebook[]

gives the current notebook into which keyboard input in the front end will be directed.

Details

  • InputNotebook returns a NotebookObject.
  • If there is no current input notebook, InputNotebook[] will return $Failed.
  • The current input notebook is the notebook to which textual commands in the front end are normally directed.
  • A palette window can be a currently selected notebook but cannot normally be an input notebook.

Examples

open all close all

Basic Examples  (1)

Give the notebook object for the current input notebook:

Wolfram Language code: InputNotebook[]

Perform additional operations:

Wolfram Language code: Options[%, WindowSize]

Properties & Relations  (1)

The notebook that starts an evaluation might not be the input notebook:

Wolfram Language code: nb = CreateDocument["document"]; {InputNotebook[], EvaluationNotebook[]}

Possible Issues  (1)

Both programmed operations and user interactions can change which notebook is taking input:

Wolfram Language code: nb = CreateDocument[{a, b, c}, WindowTitle -> "Other"];
Wolfram Language code: (SetSelectedNotebook[EvaluationNotebook[]];snb1 = InputNotebook[]; SetSelectedNotebook[nb];snb2 = InputNotebook[];)
Wolfram Language code: "WindowTitle" /. NotebookInformation /@ {snb1, snb2}
