hi Tom, thank You for quick response,

i think this is exactly the failure criterion:
“Failure to make content dismissable without moving pointer hover or keyboard focus”

Thanks for the API link, i surely will use it
I someone else would need it:

$(document).keyup(function(e) {
  if (e.key === "Escape") {
    $('ul.max-mega-menu').each( function() {
      $(this).data('maxmegamenu').hideAllPanels();
    });
  }
});

It’s worth noting that disabling “Include the search for native string functions of WordPress” in plugin options solves the problem.
