'   ' - Character sets

Anything within single quotes is interpreted as a character set. This will match if the character in the text is any one of the characters in the set. The character set can contain single characters and ranges. Thus you can define your own sets - there is a simple example of a character set,

However StrongED has a number of pre-defined Character sets which probably cover everything most users will ever need.

Some of these sets can be called by a single Character. Most have Shorthands. Some are Named. You can therefore use any of the first four columns below in the Search expression. These should not be inside '   ' single quotes.
