The UI of PCE editors is based on GNU-EMACS. Many of the basic
function of GNU-EMACS are available. Like GNU-EMACS, the PCE editors can
be programmed. Unlike GNU-EMACS however, this is not done by programming
EMACS-LISP, but by adding methods to the editor (or class editor)
and linking these methods to key-strokes.
As the basic functionality is rich and can be expanded/redefined, it
should not be very difficult to transform the PCE-editor into an editor
that is largely compatible to most available editors.
