To make configuration simpler, the editor provides two editing configurations, "Windows" and "Emacs". These editing styles configure the editor so that they behave similarly to either generic Windows editors or the GNU Emacs editor. The styles are simply particular combinations of the settings in the Editor Options dialog, so you can modify them to produce variations that you find more convenient.
To set the editor up for Windows-style editing, go to the Editor Options dialog with View > Editor Options, select the Restore page, and click Restore Windows Defaults. To set the editor up for Emacs-style editing, click Restore Emacs Defaults in the same dialog.
