Built-in Mathematica Symbol

NotebookWrite

NotebookWrite[notebook, data]
writes data into a notebook at the current selection, setting the current selection to be just after the data written.

NotebookWrite[notebook, data, sel]
writes data into a notebook setting the current selection to be as specified by sel.

NotebookWrite does essentially the same as a Paste operation in the front end: it replaces whatever the current selection in the notebook is by data.

NotebookWrite is the basic way to use the Mathematica kernel to modify the contents of notebooks that are being manipulated by the front end.

NotebookWrite automatically wraps Cell around the data you specify if this is necessary.

	After	place the current selection immediately after the data written
	All	make the current selection be the data written
	Before	place the current selection immediately before the data written
	None	leave the current selection unchanged
	Placeholder	make the current selection be the first placeholder in the data written
