Renamed a couple of Input keyboard properties to be more explicit.

app/js/ui/Input.js

     return "0";
   }
 
-  get lastaction(){
+  get lastkeyaction(){
     return KEYMAP["lastaction"];
   }
 
     return KeymapEventName();
   }
 
-  get currentCodes(){
+  get currentKeyCodes(){
     return KEYMAP["currentcodes"].map(e=>e[0]);
   }
