Google Docs simulate keyboard

Question

I need to simulate keyboard in google docs with using JavaScript to be able print or erase characters on cursor position.
Unfortunately solutions with simulating keypress event didn't work for me. I tried with and without jQuery.
After some investigation I detected that Google Docs have virtual keyboard. Clicks on virtual keys calls this function:

C.MOa = function(a) {
  this.dispatchEvent(new Q(Td, {keyCode: a}))
};

Where Td is a string "action" and Q some Event class.
What is the correct way to send this event with java script? Is there other ways to simulate keyboard in Google Docs?

Answer 1

Paste the following code in console of google docs.

const input = document.querySelector(".docs-texteventtarget-iframe").contentDocument.activeElement;
    
// Insert the character in the document and trigger the save API call
const eventObj = document.createEvent("Event");
eventObj.initEvent("keypress", true, true);
eventObj.keyCode = 105;
input.dispatchEvent(eventObj);

You will see the character "i" inserting on the document.
