Emacs commands try to be very regular. There are Meta- commands similar
to these Control- commands which work on words in much the same way as
these commands work on characters. Control-Meta- commands work in similar
ways on Lisp S-Expressions. Watch for and make use of these trends. They
can really reduce the number of things you have to remember.
--------------------------- Useful Sub-Topics ------------------------------
*** HELP ***
The magic [Help] character is Top-H (or on Ascii keyboards: Control-_ H).
It will offer help of various sorts almost anywhere at any time. In most
places, it will offer you a menu of several possible kinds of
documentation, where you must type another character to get the desired
kind of help. At such times, the following are especially useful:
[Help] C will read another character and describe its action. You should
use this to describe any commands you read about in this document
which you would like to understand in full detail. The info given
here is intended only as an index and is not complete.
[Help] ? will give you a description of the several other very useful
options available through the [Help] facility.
*** QUIT ***
Control-G aborts all currently executing operations, flushes
typeahead, and leaves you at the innermost invocation of ^R-mode.
Control-] aborts a recursive ^R-mode (such as RMail Reply -- exits
without sending any mail).

Useful META- Commands

Meta-[ goes to Beginning of Paragraph

Meta-T Meta-K
<--------- <====================>
(Transpose Words) (Kills Current sentence)
Meta-] goes to End of Paragraph
------------------------------------------------------------------------------
Useful CONTROL-META- Commands
(On an ascii keyboard, C-M-<char> is Control-C <char>)
C-M-[ goes to Beginning of Defun
C-M-Rubout or C-M-Delete C-M-K

*** EXTENDED COMMANDS ***
Meta-X runs the extended command set completing reader (MM Commands).
*** SPECIAL PREFIX CHARACTERS ***
Control-X (Dispatch Character)
reads exactly one more character. What that character is
will decide what command is run. These commands, called the
'Control-X commands' can be documented by typing Control-X ?
Control-U (Argument Prefix)
is the 'Universal' argument prefix.
Control-U digit digit ... digit non-digit-command
will accumulate the digits as a numerical argument to the
next command. For example,
Control-U 1 2 3 Control-B
moves backward 123 characters. If not followed by digits,
Control-U will multiply the arg to the next command by 4. eg,
Control-U Control-B
will move backward 4 characters - note that
Control-U Control-U Control-B
will move backward 16 characters.
*** PREFIX CHARACTERS FOR ASCII TERMINALS (Non-TV's) ***
Control-^ - Prefix Control Altmode - Prefix Meta
Control-C - Prefix Control-Meta Control-\ - Prefix Meta
These commands read the next character and adjust it appropriately.
For example, Control-C C is equivalent to Control-Meta-C and Altmode C is
equivalent to Meta-C.
*** QUOTE ***
Control-Q is the EMACS quote character. The next character typed
after it will be inserted literally into the buffer rather than
having its normal effect.
------------------------------------------------------------------------------
Disclaimer: This documentation lies about one thing. There is a difference
between Control-H and Backspace, Control-I and Tab, Control-J
and Linefeed, etc. but most of these pairs of keys do identical
things and the distinction would not be interesting to most
people, so for simplicity they are treated as synonymous here
when in fact they are not. Sophisticated users should see other
documentation for more details.
