I am trying to figure out how I could have figured that out. also is there a better page than the one I am using below to figure all these keystrokes out? http://www.math.uh.edu/~bgb/emacs_keys.html `C-q' is an Emacs-specific prefix for `quoting' the next character when you are inserting text. 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.

There seems to be considerable confusion in this thread between keystrokes and the codes they produce. Most modern keyboards report some form of scan code for each key pressed whether or not it is one of the modifier or special keys. At this stage there is no connection between the key or key combination pressed and an ASCII code.

I find that by default xterm reports ^M on pressing the enter/return key but this can further customised through XTerm or .Xdefaults.

There was no rationale. That is just what the ASCII characters are used for and a little of the history of how they got that way - though the choice of numeric code was mostly arbitrary, some of it had to do with easy processing of codes as control for printers and teletypes. If you use the characters in a non-traditional way, that is up to you, but other systems and utilities won't follow your pattern most likely. Now, in UNIX, since it doesn't end lines with a pair of ^M^J but only uses ^J, it may look like it is a RETURN, but the original designation is Line Feed.

By the time UNIX came along, it wasn't necessary to use both characters to move the paper and print head because those were virtual. So, they just used one character - the line feed. But, MS-DOS and some others continued to use the pair to mean a new line for some reason - maybe the original association with IBM, although they didn't use ASCII, but EBCDIC - another animal. So, look up an ASCII chart with explanations and you can make an educated guess on the meanings. jerry also is there a better page than the one I am using below to figure all these keystrokes out? http://www.math.uh.edu/~bgb/emacs_keys.html Cheers, Noah Peter A.

What if I want the character to replace the ^M with a new line what do I enter in the replace field? control-q control-j ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
