Once Edwin has been entered, it can be exited in the following ways:
suspend-edwin). The call to the procedure
editthat entered Edwin returns normally. A subsequent call to
editwill resume Edwin where it was stopped.
save-buffers-kill-edwin). This is like the
suspend-edwincommand, except that a subsequent call to
editwill reinitialize the editor.
suspend-scheme). When Scheme is resumed (using the command interpreter's job-control commands), Edwin is automatically restarted where it was stopped. This command is identical to the C-x C-z command of GNU Emacs.
save-buffers-kill-scheme). Control is returned to the operating system's command interpreter, and the Scheme process is terminated. This command is identical to the C-x C-c command of GNU Emacs.
