By default the LispWorks Editor emulates GNU Emacs. This is often unusable for programmers familiar only with Microsoft Windows keys and behavior: for instance, a selection is not deleted on input, and most of the commonly used keys differ.
The LispWorks editor can be switched to emulate the Microsoft Windows model instead of Emacs.
When using Microsoft Windows editor emulation the main differences are:
Altkey activates the menu bar, and does not act as
Metawhen used as the only modifier key.
