true if the message was handled; otherwise, false.

The Microsoft Windows message must be WM_CHAR, WM_SYSCHAR, WM_DEADCHAR or WM_SYSDEADCHAR. 

If the component has contained components, the message must be passed in your implementation by calling each contained component's OnMnemonic method.

An interface that returns true from TranslateAccelerator will not call OnMnemonic. Implementations can choose to perform all specific key combination handling in TranslateChar.and bypass OnMnemonic.
