LightboxGallery und Pfeile und Esc

Hallo liebe Gemeinde, auf meiner Homepage möchte ich eine photo-gallery mittels light Box einbinden. Dazu habe ich folgendes JS - schnipsel gefunden: Quelle: https://codepen.io/sidtheangel/pen/ONRKZa Das hat so weit auch ganz gut funktioniert. Weiters würde ich gerne noch 2 Funktionen hinzufügen. 1: der User soll sich mit dem Cursor - tasten (links & rechts) durch die Bilder „klicken“ können. 2: mit der ESC - tasten soll die light Box geschlossen werden. (so, als würde man auf das X klicken..) da ich allerdings keine Ahnung von JS habe und mal schwer vermute, irgendetwas im *.js file dafür verändern/hinzufügen zu müssen, wollte ich mich an euch wenden. danke schonmal für eure antworten! liebste grütze & ein fröhliches neues jahr wünschend, medhusa
