They work with both upper and lower case letters

They work with both upper and lower case letters

Factually incorrect in the real world

The truth is that it doesn't work with either caps lock on, or holding down shift, on a Mac, in Safari or Firefox to Google Chrome. The user reported that to me, and I confirmed it myself.

They work with both upper and lower case letters

Take the demo code from https://wangchujiang.com/hotkeys/ and placed it in Codepen

<script src="https://unpkg.com/hotkeys-js/dist/hotkeys.min.js"></script>
<script type="text/javascript">
hotkeys('ctrl+a,ctrl+b,r,f', function (event, handler){
  switch (handler.key) {
    case 'ctrl+a': alert('you pressed ctrl+a!');
      break;
    case 'ctrl+b': alert('you pressed ctrl+b!');
      break;
    case 'r': alert('you pressed r!');
      break;
    case 'f': alert('you pressed f!');
      break;
    default: alert(event);
  }
});
</script>

Click in the white area

type lower case r - see a pop up

type upper case r - see no popup

Conclusion, despite you thinking it does, it doesn't work as you think.

The Joomla "J" capital hotkey is hard coded as a capital letter

Maybe its a mac thing. Works perfectly on windows

Even on your code pen
type r or R
both give the same alert

note that R is not the same as shift-R

Are you telling me that Joomla has just shipped a flagship new feature and no one tested it on Mac's, the number one PC brand in the world, 15% marketshare in the USA, shipping 22.3 million Mac units a quarter?

HOW THE HELL do you type a capital R without shift or caps lock then?!!?!

ok if I enable caps lock and click into the white of the code pen and press R it doesn't work, of I then click out (blur) and then click back into the whitespace and press R (caps lock still on) then it works.

It seems like there is a bug here for sure...
