As an aid to accessibility and personal preference, Word 2002 allows you to set registry settings to specify the color that is used in wavy underlines. Wavy underlines are used to designate text marked for smart tags and for proofing errors, such as spelling errors. For example, the default spelling underline color is red, but you may want to use a different color to help you distinguish it from other wavy underline colors. The support template offers an easy way to modify these color settings without opening the registry.
Click Registry Options on the main Support.dot page to display the Set Registry Options dialog box, and then select one of the four following items, depending on the wavy underline that you want to change:
SpellingWavyUnderlineColor for spelling errors
GrammarWavyUndlineColor for grammatical errors
SmartTagUnderlineColor to label smart tags marked in the text
FormatConsistencyWavyUnderlineColor to designate inconsistent document formatting
Click Choose Color, select the color that you want to use, and then click OK.
