SEARCH PATTERN MATCHING CODES

|A	Match any alphabetic letter, upper or lower case
|B	Match a blank - single space or tab
|C	Match any control character
|D	Match any numeric digit - "0" - "9"
|F	Match any alphanumeric - a letter or a digit
|L	Match end of line:  <CR> and/or <LF>, Form feed, end of line at EOF
|M	Multi - match any sequence of zero or more characters
|N	Match any character except following character or pattern
|Pr	Access contents of text register 'r' as pattern set
|Rr	Access contents of text register 'r' as variable string
|S	Match any separator - not a letter or digit
|T	Match selected separators (terminators)
|U	Match any upper case letter
|V	Match any lower case letter
|W	Match white space - single or multiple spaces or tabs
|X	Match any character
|Y	Match multiple characters until the next pattern matches
|<	Match beginning of line (zero length match)
|>	Match end of line (zero length match)
||	Use "||" when you need to search for "|"

\<Q\ \<CTRL-Q>\
<CTRL-Q>	Literal character.  Next character, usually a control
		character, is taken literally and not interpreted.
		Allows searching and inserting of control characters
		including line editing characters and <CR>.

		<ESC> may be inserted via <CTRL-Q> but not searched for -
		To search for an <ESC> you MUST use explicit delimiters.

\<C\ \<CTRL-C>\
<CTRL-C>	BREAK character.  Will stop an iteration macro or command
		macro before next command is executed.

\_\
_	Precedes "F" or "S" to perform search/replace to the end-of-file
	instead of just the end of the text buffer.
	"_F" is equivalent to "N".

	Precedes "B", "K", "L", "T", "Z", "EM", "RM" or "YM" to indicate a
	global operation.  Used with the "EM" command, it allows a match at
	the end of the buffer to continue.

\@\
@	Precedes commands to indicate that explicit delimiters are being used.

	E.g.  @F/string/     @I'string'	     @JP.label.

\:\
:	Precedes "F", "L", "N" or "S" to suppress error handling.
	(See also switch ES 8).

	Precedes "ER", "EW", "XT", "YD" to suppress <CR><LF> from being sent.

	Precedes "RQ" to prevent <CR><LF> or <ESC><ESC> from being included
	in the input string being copied into the designated text register.


\;\
;	Shorthand for ".erJL".  Used with "ES 8 2" following the "F",
	"S" and "L" commands.  Does not clear the error flag ".er" as
	"JL" would do.

\#\
#	Represents maximum positive number 65535.  Signifies "forever" or
	"all occurrences of".
