edit \- text editor (variant of \fIex\fR\|)
is a variant of the text editor
recommended for new or casual users.
the default settings of the options are changed
so that there are fewer ``magic'' characters in regular
expressions (\fInomagic\fR),
so that more feedback is given in command changes
and so that accidental entry to
is prevented (\fInoopen\fR).
This provides a more hospitable editing environment.
Except for the default settings of these options,
the two may be used interchangeably.
