Solution 1:

To directly answer your second question.

Here is one way:

var keyPressed = {};

$(window).keydown(function(e) {
    keyPressed[e.which] = true;
}).keyup(function(e) {
    keyPressed[e.which] = false;
});

Now you can use keyPressed whenever you want to determine if a key is down:

// wherevervar key1 = 65, key2 = 66; // A and Bif (keyPressed[key1] && keyPressed[key2]) {
    // A and B are both being pressed.
}

Solution 2:

In order to detect multiple keys being held down, use the keydown and keyup events.

var keys = {};

$(document).keydown(function (e) {
    keys[e.which] = true;
});

$(document).keyup(function (e) {
    delete keys[e.which];
});
