Match Whole Word: Check this field if you want to look for the exact word or phrase specified (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. To save the information for the current line, click the "Apply" Button. Note that in the example here, Match Whole Word is not available because the Regular Expression field is checked.
