It is beyond the scope of this Help system to describe this subject thoroughly (there are good
internet resources available), but please read on if you wish to check out the basic building
blocks used in regular expressions.
Common expressions
A regular expression is a formula composed of characters that have special meanings (called
operators). Other characters are just plain letters and numbers that are searched for.
The search engine browses the target text one character at a time and stops as soon as
it finds a sequence of characters that matches the regular expression. Searches are not
case-sensitive. Note that there are various versions of regular expressions: WaveLab uses
a version that represents a good compromise between power and ease-of-use.
The term expression refers to a single character, a character class, or a sub-expression
enclosed with () or {}.
The following items are available on the Regular Expression pop-up menu:
