About 10 years ago we had a device build that emulated a keyboard, we went to an electronics specialist and he made it. We used it to measure keypress to recognition of the machine accepting that event, the key press was a knows intervals so we could gather accepted margins of error on how fast someone was able to react to an onscreen event by pressing a key on the keyboard. This was a custom piece of hardware. Unfortunately I cannot remember where we had this made.

jQuery has a .keypress method accepting no arguments that simulates a keypress.

$("#target").keypress();

Will trigger a keypress on #target

If you'd like to also select which key was pressed, you can use .trigger. This example is from the docs:

var e = $.Event("keydown", { keyCode: 8});

$("body").trigger(e);

The key code 8 is the key code for backspace in JavaScript.

Let me know how that works for you :)

If you need a function:

function simulateKeyPress(character) {
  jQuery.event.trigger({ type : 'keypress', which : character.charCodeAt(0) });
}

I recently decided to buy a new keyboard, but from my past experiences with keyboards, I was able to learn that it is also very important to get a keyboard cover keyturepro.com/shop/p/macbook-pro-keyboard-cover because with it your keyboard will always be clean, will not be scratched and will not get into it dirt and dust, so it will last you even longer.
