this solvable quite easy using jquery think. can try experiments following snippet, should want:

jquery(function() {      var inputbuffer = "";            jquery("body").keypress(function(event) {          // collect input not being processed input/textarea field          inputbuffer += string.fromcharcode(event.charcode);      });      jquery("input,textarea").focus(function(event) {          // append buffered input text field          jquery(this).val( jquery(this).val() + inputbuffer );          // clear buffer          inputbuffer = "";      });      jquery("input,textarea").blur(function(event) {          // discard input buffer          // prevent using input collected while having input/textarea in focus          inputbuffer = "";      });  });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <div>      <p>some non-input element</p>  </div>  <input type="text" />
