A Key can never contain an equal sign ('=')
While we disallow typing '=' inside the Key column
we cannot prevent the user from pasting text that contains a '='
This leads to strange effects since when we insert the Key/Value pair into
the Strings property, in effect the equal sign will be treated (by design) as the separator for the value part.
This in turn updates the Value column, but does not remove the equal sign from Key.
E.g. if both Key and Value celss are empty and you type '=' into an empty Key cell,
the Value cell will become '=='
