	Brief Regular Expressions
Brief Regular Expression		Definition
X\:,n2?		Minimal match of at least zero occurrences but not
		more than n2 occurrences of X.
X\:n1,n2?		Minimal match of at least n1 occurrences but not
		more than n2 occurrences of X.
\(X\)		Matches sub-expression X but does not define a
		tagged expression.
{X}		Matches sub-expression X and specifies a new
		tagged expression. See Using Tagged Search Ex-
		pressions for more information.
{@dX}		Matches sub-expression X and specifies to use
		tagged expression number d where 0<=d<=9. No
		more tagged expressions are defined by the sub-
		expression syntax {X} once this sub-expression
		syntax is used. This is the best way to make sure
		you have enough tagged expressions.
XY		Matches X or Y.
[char-set]		Matches any one of the characters specified by
		char-set. A dash (-) character may be used to
		specify ranges. The expression [A-Z]matches any
		uppercase letter. Backslash (\) can be used inside
		the square brackets to define literal characters or
		define ASCII characters. For example, \- specifies a
		literal dash character. The expression [\0-\27]
		matches ASCII character codes 0..27. The expres-
		sion []] matches a right bracket. In SlickEdit® regu-
		lar expressions, [] matches no characters. In both
		syntaxes, the expression [\]] matches a right brack-
		et.
[~char-set]		Matches any character not specified by char-set.
		A dash (-) character may be used to specify ranges.
		The expression [~A-Z]matches all characters ex-
		cept uppercase letters. The expression [~] matches
		any character except newline.
[char-set1 - [char-set2]]		Character set subtraction. Matches all characters in
		char-set1except the characters in char-set2.
		For example, [a-z-[qw]]matches all English lower-
		case letters except q and w. [\p{L}-[qw]]matches
