I assume (dangerous business), that, in the cardScript of the card that 
holds your table
one could have this sort of thing:

on keyUp KUP
    if KUP =

wait a minute; scrub that . . . let's go for rawKeyUp:

on rawKeyUp RUP
    if RUP = 65289 then
     --  do whatever fancy things you want
    end if
     -- trap left arrowKey
    if RUP = 65361 then
    --  do whatever fancy things you want
    end if
    -- have further routines to trap the other arrow keys
end rawKeyUp

[if that doesn't thrill your gorilla overmuch, consider using a switch 
statement]

I suppose you would have to have this sort of script in the field's script:

on closeField
   -- do whatever you fancy
end closeField
