I am setting accesskeys for basically all buttons on my page, and I realize that for some onclientclicking button, which be clicked will trigger some popups, if you set accesskey for them then popup windows will keep coming like you are keep clicking the button even you just did once. it works fine on chrome but that problem can't be fixed on IE, so is there any way that we can do like set_cancel(true) for a onclientclikcing method, for those accesskeys?
