Hi list,

While editing with Org column view, I'd like some easy navigate and modify keys.
In the patch attached (against git version), I bind vi-style key
h,j,k,l to move around, and numeric key 1-9,0 to set the nth (actually
'1' is the first, and '0' is the last) allowed value.

I mock up this by copying org-columns-next-allowed-value and modifying a bit.
Hope it is useful.

-Levin
