ItemFocusOut not catching "TAB" key in Datagrid edited cell?

Question

In DataGrid, "keyUp" can catch "TAB" key when it is pressed,
but the Keyboard event has less information needed. I tried
itemFocusOut, but it seems DataGridEvent would not catch it. Any
tips on how to make "TAB" key generate DataGridEvent or similar
event?
Platforms with this issue: WIN-XP/JDK-1.6/Air-1.5/FLEX
SDK-3.2
Thanks!

Let me rephrase like this:
In our application, a DataGrid’s edited cell has
“itemEditEnd” and “itemEditBeginning”
handlers defined. However when a “TAB” key is pressed
to navigate from one editable cell to another editable cell, none
of the above handlers can catch this special key stroke event.
Our intention is to make “TAB” key to emit an
event that can be caught by above handlers. Or, in other words, we
would like make “TAB” key to be similar(in the sense of
generating events) to that of “Enter” key when pressed.
