The problem was solved with this

window.onload = function () {
     "use strict";
     // load both text files
     textFile(0);
     textFile(1);
     document.getElementById("start").onclick = function (e) {
         var i;
         requestFullScreen();
         i = (e.ctrlKey)
             ? 1
             : 0;
         init(i);
     };
};

A couple of comments. Instead of

     textFile(0);
     textFile(1);

initially I had tried to use an for loop, which worked but JSlint found 
the for unexpected, so I deduced that I shouldn't use a for loop in this 
context.

Also I still have difficulty understanding why the e is now necessary in 
the line:

     onclick = function (e) { ...
