If the objects involved are just plain TextFields, all that is
required is to link up the nextText outlets in IB.  Provided you
#import <appkit/TextField.h>, the above code should work OK.

The situation is more involved if you have a Matrix of TextFieldCells,
or a Form (which is of course a subclass of Matrix).  Matrix's
(and, by inheritance, Forms) only look at "nextText" when you get
to the last Cell in the Matrix; tabbing from Cell to Cell within
a Matrix or Form is handled automatically.  Furthermore, for some
reason Matrix does not implement a "nextText" method.  But anyway,
see the documentation on the TextDidEnd:endChar: method of Matrix
for a description of how this works.
