Our current version of zurb reveal modal does not support disabling this behaviour. The code responsible of this trigger is in jquery.foundation.reveal.js:
//
// Bind keyup functions on the body element.
// We'll want to close the modal when the 'escape' key is hit.
//
$( 'body' ).bind( 'keyup.reveal', function ( event ) {
//
// Did the escape key get triggered?
//
if ( event.which === 27 ) { // 27 is the keycode for the Escape key
//
// Escape key was triggered.
// Trigger the modal 'close' event.
//
modal.trigger( 'reveal:close' );
}

}); // end $(body)

Thanks Daniel, that at least allowed me to come up with an easy temporary patch by commenting out the trigger. That will probably prevent ESC from being used to close windows all over the place, but the mouse should work just as well for that. :-)
