Options
.PP
Each instance of the editor has a set of options,
which can be set to tailor it to your liking.
The command
.I edit
invokes a version of
.I ex
designed for more casual or beginning
users by changing the default settings of some of these options.
.PP
There are three kinds of options:
Boolean,
numeric,
and string options.
Options are controlled by the
.I set
command
which can be used to show their current values
or to assign new values.
The options,
their defaults,
and a short description of each are given in the following table.
A more complete description of each option will be given near the
end of this reference manual.
