=== 使い方 ===
KeySnail の prompt 内で Bing 検索を実行し、結果を表示します

キーマップを変更したい人は、次のような設定を .keysnail.js の PRESERVE エリアへ
>|javascript|
plugins.options["quick_bing.keymap"] = {
    "C-z"   : "prompt-toggle-edit-mode",
    "j"     : "prompt-next-completion",
    "k"     : "prompt-previous-completion",
    "g"     : "prompt-beginning-of-candidates",
    "G"     : "prompt-end-of-candidates",
    "D"     : "prompt-cancel",
    // specific actions
    "o"     : "open-current-tab,c",
    "O"     : "open-new-tab,c",
    "C-o"   : "open-background-tab,c"
};
||<

コマンドを追加したい場合は、こんな感じで
>|javascript|
shell.add(
    ['bing'], 'Quick Bing search',
    function(args) ext.exec('quick-bing', args.join(' ')),
    {
        argCount: '*',
        completer: function(args, ex) completer.fetch.google(ex.left || '', ex.whole || '')
    },
    true
);
||<

===なんで Bing===
XML で出力してくれるから。それ以上の理由はありません
