Question

I am developing a web application, I need to use keyboard to open/switch tabs in following ways,

1. When I press ctrl + alt + 1 tab1 should open.
2. But without releasing ctrl and alt if I press 2 tab2 should open.

I am able to achieve 1 and 2 but with releasing ctrl and alt keys.

Answer 1

Obviously the way you have used to find the pressed keys is not good when it has ctrl & alt. You can simply listen for the ctrl+alt+1 and ctrl+alt+2 like this,

$(document).keydown(function (e) {
    if (e.ctrlKey && e.altKey) {
        // 97 for key "1"
        if (e.keyCode == 97) {
            // open first tab
            $("#Tab1").click();
        }
        else if (e.keyCode == 98) {
            // 98 for key "2"
            // open second tab
            $("#Tab2").click();
        }
    }
});
