cell movement using Tab/Rtn

["joshua lambert" <lambert_joshua stumail emporia edu>]

Hi,
I would like to switch from using Excel to Gnumeric but cannot find a
specific feature I use very often.  In Excell, if I enter data in cell
A1, press Tab, enter data in B1, and then press enter; cell A2 is
highlighted and ready to type.  In Gnumeric the same keystrokes take me
to B2.  Is there an alternate key that can get me to A2?

Context:
I realize Return + Home will do the same thing but it is cumbersome
keeping one hand on the keypad and moving the other between the Home and
Tab keys.  What I need it for is very repetitive and very simple (and
very boring) but the extra keystroke and hand movement add about 1/4
more time to the task.

Thanks.
