how can I simulate (trigger) multiple keypress upon press of a button using javascript (javascript and html), while having the window being the event target.

I basically wish to create a button, when it's clicked, it will simulate (trigger) ctrl+w

I was trying to mix and match and try lots of different codes around this subject, but couldn't get the multiple key press to work properly. In addition, because I am new to javascript I don't yet fully understand how to turn all of this into a function that can be called upon press of a button.

Have a nice day, looking forward to the answers.
