currentCard vs current card

[Paul Dupuis]

In LC968 or 969rc2 the Dictionary has an entry for the 'currentCard' 
used either as a property:
put the currentCard of stack "X" -- put the short name of the currently 
displayed card in stack X

It appears the following syntax is also valid, but slightly different:

puttheshortnameofcurrent card ofstack "X"

Yet, I can find no entry for the 'current' keyword in the Dictionary? Is 
this a Dictionary omission?
