   3  * http://blog.livedoor.jp/tzifa/archives/50776590.html\r
   4  *  keydown について。Firefox では押している間中リスナの関数が実行される\r
   5  *  デフォルトイベントの制御・抑止 (opera)keypress を用いる。\r

   7  * キーイベント処理の工夫\r

   9  *  keydown/up時にピリオドが文字化け (IE4-6) IE4+では「keypress」でキーコードを処理する 但しCtrlやALTが押されている場合は逆にkeydownで処理する必要があります\r

  13  *  1. テンキーの 0～9 keyCode:96-105\r
