超適合水球王的功能，如果你為了在一堆水球裡找電話苦惱、如果你為了在一堆水球裡

  找某個關鍵字苦惱，在水球列表下，按 f 鍵，將會自動找出

  含有該特定關鍵字的所有水球，連id也一併找。

  完整版的水球搜尋功能，bmw_item()部分是頗吃資源的東西，不一定要換，如果站夠小

  機器夠Power，那就換吧!


: bmw.c

  bmw_item()換成下面那隻，要讓水球裡的關鍵字變色的bmw_item()就是這樣。

  如果怕日後維護困難(指標飛來飛去的三天後我一定會忘記我自己在寫什麼，所以這點

  站長自己要有備案以防萬一)，就把舊的bmw_item()用#if 0包起來，留著日後用。
