To write a keyboard related application I wanted the list of the ASCII codes of the keys that I have on my keyboard.
It is a windows keyboard :
You can get all the keyCode values (even for Function keys) by running (injecting) following JavaScript code into your browser's console. Paste the following code and press enter. Then click anywhere in the page to remove the cursor from the console.
Then press any key for which you want a keyCode in Hex
Here is the code :
document.addEventListener("keydown", function (e) {
code = (e.keyCode);
console.log("In decimal "+e.keyCode);
var hex = code.toString(16);
console.log("In hex "+hex);
}, false);
