How to prevent right click to open jupyterlab's menu?

[Roy-Kid]

Hi, I wonder how to prevent right click to open jupyter menu, but just affects the widget itself. I find this snippet from https://github.com/superstar54/weas-widget/blob/fea56fce2c4a7070f1cbd5803694f243548a94fb/js/widget.js#L244, and apply on el of render({model, el}), but it doesn't work. Can I ask how to fix it?

You probably need to stop propagation of the contextmenu event.
Something like this: el.addEventListener("contextmenu", e=>e.stopPropagation())

you're a genius, bro! fixed!

function preventEventPropagation(element: HTMLElement) {
  const stopPropagation = (e) => e.stopPropagation();
  ["contextmenu"].forEach((eventType) => {
    element.addEventListener(eventType, stopPropagation, false);
  });
}

But no matter which part I select in the cell's output, once I press "R," the cell type will be converted to raw, even if I add "keypress" and "key up " to the list. If you happen to know the answer, could you please help me again?

Also, I believe it's a good feature for those developers whose's widget need to use shortcut?

You're probably looking for keydown event this time =)
