Is there a way to detect find on the page searches in javascript

Question

each browser has find on page functionality (ctrl+F). Is there a way to detect user searches in javascript so that I could attach additional actions.

Answer 1

As initially suggested by @Nicola Peluchetti, here is a slightly improved version by feature sniffing:

window.onkeydown = function(e){
    var ck = e.keyCode ? e.keyCode : e.which;
    if(e.ctrlKey && ck == 70){
        alert('Searching...');
    }
}
