The wantTabs property forces a text field to insert TAB characters in the text when the user presses the TAB key.
By default, text fields like TextEdit do not insert a TAB character in the text when the user presses the TAB key, since the TAB key is used to move to the next field. You can force the field to use TAB keys with this property.
The user can still jump out of the field with Shift-TAB, if this key is not bound to an action.
