This way, you can enter special characters, like C-a, C-b, C-c, ... C-z while you are typing text. Just hitting the respective control-key combination may be bound to an Emacs command. The relevant text from the Emacs manual describes this much better than me: Only printing characters and <SPC> insert themselves in Emacs. Other characters act as editing commands and do not insert themselves. These include control characters, and characters with codes above 200 octal. If you need to insert one of these characters in the buffer, you must "quote" it by typing the character `Control-q' (`quoted-insert') first. (This character's name is normally written `C-q' for short.) There are two ways to use `C-q': * `C-q' followed by any non-graphic character (even `C-g') inserts that character. * `C-q' followed by a sequence of octal digits inserts the character with the specified octal character code. You can use any number of octal digits; any non-digit terminates the sequence. If the terminating character is <RET>, it serves only to terminate the sequence. Any other non-digit terminates the sequence and then acts as normal input--thus, `C-q 1 0 1 B' inserts `AB'. The use of octal sequences is disabled in ordinary non-binary Overwrite mode, to give you a convenient way to insert a digit instead of overwriting with it. This is from section 8.1 (Inserting Text), of the Emacs 22 manual. I hope this helps :-)
