| { } | Braces group characters or expressions. Groups can be nested, with a maximum number of 10 groups in a single pattern. . For the Replace operation, the groups are referred to by a backslash and a number according to the position in the ?Text to find? expression, beginning with 0. For example, given the text to find and replacement strings, Find: {[0-9]}{[a-c]*}, Replace: NUM1, the string 3abcabc is changed to NUMabcabc. |
| A backslash before a wildcard character tells the IDE to treat that character literally, not as a wildcard. For example, ^ matches ^ an d does not look for the start of a line. |
