Match Whole Word: The Match Whole Word flags in the Main Window and the Script Editor determine whether Search & Replace will search for the exact word or phrase specified. A "whole word" is one that is enclosed by whitespace. For example, if this option is on and you look for "Window", the program will find it in the phrase "...use the Window menu..." but not in the phrase "...Windows 95...". If this option is not checked, both occurrences will be found. Match Whole Word is not available when Regular Expressions are in use.
