Reset to default 10You can detect it using the following function:
document.addEventListener("keydown", function (event) {
event.stopPropagation();
event.preventDefault();
if(event.ctrlKey && event.keyCode == 81)
{
console.log("CTRL + Q was pressed!");
}
else
{
console.log("Something else was pressed.");
}
});
The stopPropagation() and preventDefault() calls prevent the browser's default behaviour from occurring.
If you want to detect other keys, this page is rather useful: http://asquare/javascript/tests/KeyCode.html
