Assuming you are using my .emacs, here is a summary of the behavior you
should get when using XEmacs ("xemacs") or GNU Emacs ("emacs") on
X-Windows or on ttys (dumb terminals).

(A) ON BOTH GNU EMACS AND XEMACS WHEN RUNNING UNDER X WINDOWS
o M-l (ie ESC then lowercase L or Alt-l) will start Lisp. If Lisp is
  already started, then M-l just switches you there. You can
  also use the pulldown "Buffers" menu to switch among any existing
  buffers.
o Within the buffer running Lisp, M-p will scroll through the
  previously entered forms. So if you just typed in a complicated
  expression and want to do almost the same thing, M-p will pop it
  back up, then you can edit it and hit RETURN.
o For filenames ending .lisp or .lsp:
  - They will get "fontified" with function name in one color, 
    comments in another, etc. This will also work for C, C++, Pascal,
    and Prolog files. 
  - RETURN will take you to next line plus indent to proper level.
  - If you hit TAB the current line will be reindented to proper
    level, no matter where on the line the cursor is.
  - If the cursor is inside a function definition, then
    hitting C-x d will compile the definition of that function.
    You will stay in current Lisp source code buffer.
  - If the cursor is inside a function definition, then
    hitting C-x d will compile the definition of that function.
    You will stay in current Lisp source code buffer.
  - If the cursor is inside a function definition, then
    hitting C-x C-d will compile the definition of that function.
    You will switch to the buffer that is running Lisp.
  - When you type a R paren the matching L paren will briefly blink.
o Doing M-x clman will prompt you for a Lisp function or variable
  name, and then print the manual page for that with highlighting in
  various fonts. You can print out this buffer for permanent info.

(B) ON XEMACS ONLY (WHEN RUNNING UNDER X)
o You will have a Lisp pulldown menu that gives you access to all
  of the above functionality plus a bunch more.
o The File pulldown menu will have 2 entries that let you print
  the source code maintaining some of the font info (see the 
  Intro-Functions.lisp I handed out - it was printed this way).
  Note that this will also work for C or C++ or Pascal or Prolog
  files, or for the buffer that is the output of clman.
o When the cursor is next to a R paren, the matching L paren will 
  blink on and off.

(C) ON XEMACS ONLY (WHEN RUNNING ON TTYS (IE NON-X))
o You will get a more limited "fontification" of code. Works for
  at least Lisp, C, C++, Pascal, and Prolog.
o You can still print the code maintaining this font info. C-x p
  prints whole buffer. C-x C-p prints only the currently selected
  region.
o M-l still starts Lisp, M-p still scrolls through previous input
  in Lisp, C-x d still sends a function definition over to Lisp,
  C-x C-d still sends the definition over plus takes you to Lisp,
  matching parens will still blink as they are entered, 
  autoindentation will still be done, and M-x clman will still
  print out a Lisp manual page (albeit with more limited font
  highlighting).

(D) ON GNU EMACS (WHEN RUNNING ON TTYS (IE NON-X))
o M-l still starts Lisp, M-p still scrolls through previous input
  in Lisp, C-x d still sends a function definition over to Lisp,
  C-x C-d still sends the definition over plus takes you to Lisp,
  matching parens will still blink as they are entered, 
  autoindentation will still be done, and M-x clman will still
  print out a Lisp manual page (albeit without font highlighting).
