Set WantReturns to true to allow users to enter return characters into the text. Set WantReturns to false to allow the form to handle return characters instead. 

For example, in a form with a default button (such as an OK button) and a memo control, if WantReturns is false, pressing Enter chooses the default button. If WantReturns is true, pressing Enter inserts a return character in the text.

If WantReturns is false, users can still enter return characters into the text by pressing Ctrl+Enter.
