7.1.1. Notes on the Tables
emacs commands use the Control key and the Meta key
(Meta is usually the Escape key).
In this chapter, the notation C- indicates that
the Control key is pressed at the same time as the character that follows.
Similarly, M- indicates the use of the Meta key.
When Meta is simulated by the Escape key,
it's not necessary to keep the Meta key pressed down
while typing the next key.
But if your keyboard actually has a Meta key, then it is just like
Control or Shift, and you should press it simultaneously with the
other key(s).
In the command tables that follow, the first column lists the keystroke
and the last column describes it. When there is a middle column,
it lists the command name. This name is accessed by typing
M-x followed by the command name.
If you're unsure of the name,
you can type a space or a carriage return,
and emacs lists possible
completions of what you've typed so far.
Because emacs is such a comprehensive editor,
containing literally thousands of commands, some commands
must be omitted for the sake of preserving a “quick” reference.
You can browse the command set by typing C-h
(for help) or
M-x (for command names).
