+ | * [abc] will find any of the letters a, b, or c. | ||
+ | * [F] will find upper case “F” | ||
+ | * [Fred] will find " | ||
+ | * Groups | ||
+ | * Round brackets are used in pairs to enclose //groups//. For example: | ||
+ | * '' | ||
+ | * They must be used in pairs and are addressed by number in the replacement. In the replace field, \1 represents the first group, \2 represents the second group, and so on. For example: | ||
