Tagged expression	{}	Marks the text that matches the expression in parentheses.
Nth Tagged text	\N	In the Find or replace expression, indicates the text that the nth tagged expression matches, where n is a number from 1 to 9. In the Replace expression, you insert the entire matched text.
Right-aligned fields	\ (w,n)	In the Replace expression, right-aligns the nth-tagged expression in the field to at least W character justifies.
Align Left field	\ (-w,n)	In the Replace expression, the nth marked expression in the field is left-aligned at least W -character justifies.
Prohibit match	~ (X)	Suppresses the match when X appears at this position in the expression. For example, de>real~ (ity)???? De> matches "real" in "realty" and "really", and does not match "real" in "reality".

Alphabetic characters	: C	Match expression ([a-za-z]).
Decimal number	:d	Match expression ([0-9]).
Hexadecimal number	: H	Match expression ([0-9a-fa-f]+).
Identifier	: I	Match expression ([a-za-z_][a-za-z0-9_][a-za-z0-9_]*).
