Recipe 6.2. Finding JOE Commands
6.2.1 Problem
How do you make
JOE do anything useful? You want a complete command reference for
JOE, in all of its personalities. And you want it online, so you can
use it while you type.
6.2.2 Solution
Turn on the online help, which is present in every one of
JOE's personalities.
To start up JOE with the Help screen turned on, use:
$ joe -help
Do the same for rjoe, jpico, jmacs, and
jstar.

JOE uses a lot of three-key commands. The caret
(^) is the Ctrl key. Hit the first two
keys (e.g., ^K) together,
