I just chanced upon a web page that seemingly remapped my default alt + f4 function to search on the website. When on that web page (a university webmail), whenever i press alt + f4, it goes to the search function rather than closing the browser.
How is this even possible? Being a university webmail, it is a fairly harmless effect (annoying but harmless) but if it can be remapped to open the search function, it could be remapped to do many other things. Is there any way to protect against this?
