Trigger event on hold of shift+enter key

Question

I was trying to call a function on the press of the shift + enter key.

What I was trying is this

$('.o_searchview_input').on('keydown', function(event) {
debugger;
  if (event.keyCode == 13 && !event.shiftKey) {
    $(this).trigger(jQuery.Event("keydown", {
      keyCode: 13, // ENTER
      shiftKey: true
    }));
  } else if (event.keyCode == 13 && event.shiftKey) {
    console.log('shift + enter');
  }
});

But it is pressing the shift key automatically.

I am worried is there any option in JavaScript to trigger an even on the press of two keys?

There is no event that checks if multiple keys are pressed. If you want to check for 2 keys you will need to create keydown and keyup events to track which keys are pressed but not released manually.

The exception to this rule is Shift Alt and Ctrl/Cmd These are known as key modifiers and can be used like in your example:

if (event.keyCode == 13 && event.shiftKey) // do something

Using event.preventDefault() on shift + enter does the job for you

$('.o_searchview_input').on('keydown', function(event) {
  if (event.keyCode == 13 && event.shiftKey) {
    event.preventDefault(); // prevent default action
    console.log('shift + enter');
    // call your function
  }
});

`Enter` adds new line, Where as `Shift + Enter` is prevented
<textarea class="o_searchview_input"></textarea>
