GNU Emacs key notation
For the rest of this chapter, we'll be switching to GNU Emacs' form of
representing the keystrokes you'll type. This may be confusing at
first, but you'll get used to it quickly. Here are our form and GNU
Emacs' form:
Table 4.1: Emacs Notation
Our Notation GNU Emacs'
--------------------------------
[t] t
[CTRL-t] C-t
[RETURN] RET
[DELETE] DEL
[SPACE BAR] SPC
In addition, GNU Emacs makes extensive use of the [META] key. This
key acts much like the [SHIFT] and [CTRL] keys; you hold down the
[META] key while pressing another key. [META] keystrokes will be
indicated by M- ; for example, [META-t] will be printed M-t.
If you don't have a [META] key on your keyboard (or if you don't know
of any special key to use for that purpose), you type a two key
sequence: first press and release the [ESC] key, and then press the
other key. Thus, M-t would be typed by pressing and releasing the
[ESC] key followed by pressing and releasing the [t] key. For M-C-t,
press and release the [ESC] key, then hold down the [CTRL] key and
press [t]. Finally, release the [CTRL] and [t] keys. (It sounds a lot
harder than it really is!)
