How do I find special characters inside a document?
[^!:,;?\. [:alnum:]]*
 * use the  menu;
 * in the Find area, enter:


 * click the More Options button;
 * check Regular Expressions; and
 * click Find all.

Explanations:
 * ^ at the beginning of the enumeration between brackets ( [^ ) means “all that is not between brackets.” It is possible to complete the list depending on what is looked for. For example [^!:,;?\.+-%$€ [:alnum:]]*


 * [:alnum:] matches an alphanumeric character;
 * the * character is a wild multiplier allowing you to find the characters defined previously (here, the ones listed between the brackets) regardless of how often they occur.
