Default Environment Variables
I'm using ksh on an AIX system.

I know that env will list the values of environment variables that have been set. How do I find out about other environment variables?

Here's what happened:

I recently took a new job at a competitor. One thing that attracted me to the job, and vice versa, is that the primary business software is from the same vendor, and running on the same type of system.

My problem was, a little shortcut I got used to was missing. At a shell command prompt, hitting esc then k would return the prior command to the command line, editable with vi commands. (FYI: Hit k multiple times to scroll thru recent commands. Hit j to scroll the other way.)

This was missing for days, until I added the following line to my .profile:

EDITOR=vi ; export EDITOR

Simple enough, but I got the idea to add that line out of the blue. I really don't know why I thought to try it, but it REALLY got me wondering if there were any other useful commands and environment variables that I'm unaware of.

Thanks.

vconsole.conf

VCONSOLE.CONF(5)                                                   vconsole.conf                                                  VCONSOLE.CONF(5)

NAME

       vconsole.conf - configuration file for the virtual console

SYNOPSIS

       /etc/vconsole.conf

DESCRIPTION

       The /etc/vconsole.conf file configures the virtual console, i.e. keyboard mapping and console font.

       The basic file format of the vconsole.conf is a newline-separated list environment-like shell-compatible variable assignments. It is
       possible to source the configuration from shell scripts, however, beyond mere variable assignments no shell features are supported,
       allowing applications to read the file without implementing a shell compatible execution engine.

       Note that the kernel command line options vconsole.keymap=, vconsole.keymap.toggle=, vconsole.font=, vconsole.font.map=,
       vconsole.font.unimap= may be used to override the console settings at boot.

       Depending on the operating system other configuration files might be checked for configuration of the virtual console as well, however only
       as fallback.

OPTIONS

       The following options are understood:

       KEYMAP=, KEYMAP_TOGGLE=
           Configures the key mapping table of for they keyboard.  KEYMAP= defaults to us if not set. The KEYMAP_TOGGLE= can be used to configured
           a second toggle keymap and is by default unset.

       FONT=, FONT_MAP=, FONT_UNIMAP=
           Configures the console font, the console map and the unicode font map.  FONT= defaults to latarcyrheb-sun16.

EXAMPLE

       Example 1. German keyboard and console

       /etc/vconsole.conf:

           KEYMAP=de-latin1
           FONT=latarcyrheb-sun16
