Setup

var keyCode = 100;
var keyCodeRanges = [
                [48, 57],    // 0-9
                [65, 90],    // a-z
                [96, 107],   // Numpad0-Numpad9(96-105), NumpadMultiply(106), NumpadAdd(107)
                [109, 111],  // NumpadSubtract(109), NumpadDecimal(110), NumpadDivide(111)
                [186, 192],  // ;=,-./
                [219, 222]   // [\|]'
