Data grid, cut and paste

[Sadhu Nadesan]

Trevor,

Cut and paste is not working in my data grids, with standard windows 
shortcuts, like, Ctrl-X, Ctrl-C, Ctrl-V.  (nothing happens).  But when I 
create a simple test stack with the only object a simple data grid, 
these keyboard short cuts work fine.  I haven't removed any of the code 
in the column behavior scripts - any idea why this is happening?  None 
of my menu shortcuts uses X, C, or V.  Or any idea what to do about it, 
such as, should I try to code this functionality as choices on an edit menu?

I want to be able to copy from one cell to another, with Ctrl-C to copy 
in cell A, and Ctrl-V to paste in cell B.

Thanks for any advice!
