About the correct keyboard setting
This feature and some of the options described in this Help topic are only available if you are using the Korean language version of Microsoft Office, or if you have installed the Office 2003 Multilingual User Interface Pack or Office 2003 Proofing Tools for Korean. In addition, you must enable support for Korean through Microsoft Office Language Settings. The correct keyboard setting applies only to Korean text.
The Correct keyboard setting option (Tools menu, AutoCorrect Options command, AutoCorrect tab) automatically corrects words entered in English mode that were meant to be entered in Hangul mode, and vice versa.
The correct keyboard setting also automatically corrects English words that have a Hangul ending entered in English mode. The setting works even when Hangul and English are mixed.
