There is no property to set. Look through the code I see that you need  
to make sure and pass OpenNextFieldEditor in order for tabbing to  
work. Any chance you are capturing that message but not passing?

Otherwise as long as you have > 1 column in your data grid tabbing  
will just work by default. I just tested by:

1) Dragging a data grid table onto a new stack
2) Adding two columns worth of data
3) Double-clicking on column 1 to edit
4) Pressing tab key.

I'm not aware of any way to break this unless you a) customized your  
column template and turned autotab off or b) have a script getting in  
the way of the tabKey message or c) have a script execution error that  
occurs while messages are being fired off during tabkey.

You could always trying editing the "field editor" script in the data  
grid library and seeing if the tabkey message is being called. You  
could follow the code through from there.

1) Make sure 'the preservevariables' is true.
2) Edit script of button "field editor" of stack "revdatagridlibrary"
3) Edit script of button "data grid" of stack "revdatagridlibrary"
