  Jed is the default editor in INX, for these reasons:
  
  * You can explore menus with your mouse, which helps to learn the key bindings.
  * It is fairly intuitive compared to vi, which is the "standard" nix editor.
  * It has pretty colours ;-)
  
  Also included is the tiny "zile" editor. Jed and zile both emulate Emacs.
  
  Recommended: If you want to learn Jed (or indeed Emacs), run the zile editor 
  and try the tutorial. The zile tutorial helps with all three.

  Vi or Vim will be on any GNU/Linux or Unix installation. 
  Knowing your way around vi is always useful.
  
  * Vim has a tutorial - just type "vimtutor" at the command line prompt.
  * Vi/Vim is a "modal" editor - this means it has a "command" mode and an "input" mode.
    You switch by hitting the <escape> key. This is explained in "vimtutor".
  * Vi/vim is very powerful - whenever you see the word "powerful" associated 
    with a *nix app, expect a long apprenticeship ;-)

  The "dvtm" "Dynamic Virtual Terminal Manager" is included in INX.
  
  You can use it either in a tty (virtual terminal) or in GNU Screen.
  It acts as a "tiling terminal manager" that splits the screen into
  separate terminals, each of which can be used independently.
  
  The "modifier" key combination (Mod) is "CTRL+g". There are several
  possible ways to manipulate the splits, and so on. If you start 
  dvtm from here, you will see the manual that will help you
  to get started with using it. The main thing to read in the manual
  is the section "Keyboard Commands" that gives the "Mod" key strokes.
  
  You can then create new terminals, and have the manual as a "cheat sheet" 
  visible to guide you. 
  
  As a first action, try: ctrl+g c
  To move back and forth between terminals: ctrl+g [1...n] is probably the 
  easiest way to start (For example, ctrl+g 2 , ctrl+g 1 and so on).
  
  The dvtm man page is not too scary ;)
