 * @author         teramako teramako@gmail.com
 * @version        0.1b
 * ==/VimperatorPlugin==
 *
 * 英語での説明を放棄する
 *
 * keyイベント(正確にはkepressイベント)をWebコンテンツ側へ送る事を可能にするプラグイン
 * Gmailとかlivedoor ReaderとかGreasemonkeyでキーを割り当てている場合に活躍するでしょう。
 * それ以外の場面ではむしろ邪魔になる諸刃の剣
 *
 * :f[eed]map lhs           -> lhsのキーマップをそのままWebコンテンツへ
 * :f[eed]map lhs [num]rhs  -> lhsのキーマップをrhsへ変換してWebコンテンツへ
 *                             [num]はフレームの番号(省略時はトップウィンドウへイベントが送られる)
 *
 * :fmapc
 * :feedmapclear            -> 全てを無に帰して元に戻す
 *
 * :f[eed]map! lhs          -> "!" をつけると、仮想キーコードでイベントを送るように
 *
 * == LDR の場合 ==

  'js plugins.feedKey.setup("j k s a p o v c <Space> <S-Space> z b < >".split(/ +/));');
EOF
 * とかやると幸せになれるかも。
 *
 * == Gmail の場合 ==

  ');'
].join(''));
EOF
 * とかやると幸せになれるかもしれません。
 * 頭についている3の意味は3番目のフレームの意味。通常のmapと違い3回の意味ではないので注意
 *
 * Greasemonkey LDRizeの場合などにも使用可
 *
 * ※ 2008/11/1 に fmaps コマンドを追加
 *
 * .vimperatorrc に以下を追加することで、上記と同様のことができます。
