The Wolfram Language allows any front end command to be executed programmatically from within the kernel by sending an appropriate front end token. There are tokens for all standard menu commands—as well as ones not accessible directly with the default front end menu configuration.

FrontEndTokenExecute — execute a menu-like command specified by a front end token

"Open" — open notebook or other files

"Close" — close the current notebook

"Save" — save the current notebook

"SaveRename" —save the current notebook under a new name

"Revert" — restore the current notebook to its last saved version

"SystemPrintOptionsDialog" — open the Page Setup dialog

"PrintOptionsDialog" — open the Printing Options dialog

"HeadersFootersDialog" — open the Headers/Footers dialog

"ShowPageBreaks" — display page breaks on screen

"PrintDialog" — open the Print dialog to print the current notebook

"FrontEndQuit" — quit the Wolfram System
