IBM ThinkPad Butterfly keyboard
IBM ThinkPad 蝶型鍵盤

The TrackWrite™, also known as the butterfly keyboard, is a foldout laptop computer keyboard designed by IBM for the ThinkPad 701 series, released in 1995. It allowed the 701 series to be both compact (when closed) and comfortable to use (when open), despite being just 24.6 cm (9.7 in) wide with a 26.4 cm (10.4 in) VGA LCD. However, as later laptop models featured progressively larger screens, the need for a folding keyboard was eliminated; consequently, no model but the 701 utilized the butterfly keyboard.

IBM註冊的商標TrackWrite，也就是大家所知道的「蝶型鍵盤」(原文：butterfly keyboard)
在1995發表的IBM折疊式膝上型電腦，ThinkPad 701系列，它具備兩項特點，即收起來的時候外型更輕巧而且在打開使用時更舒適，儘管配備寬度為24.6 公分 (9.7 英吋)的機身和寬26.4公分(10.4 英吋)的液晶瑩幕.然而後來的膝上型電腦，逐漸具備大螢幕，不再需要折疊型的鍵盤，因此，只有701系列採用這項名為「蝶型鍵盤」的技術。


The butterfly keyboard is split into two roughly triangular pieces that slide as the laptop's lid is opened or closed. As the lid is opened both pieces slide out to the sides, followed by one piece sliding downward. The two halves mesh like jigsaw puzzle pieces to form a keyboard 29.2 cm (11.5 in) wide which overhangs the sides of the laptop body. Conversely, as the lid is closed one piece slides back, then both slide inward until the keyboard can be covered by the lid. The movement of the keyboard is driven by a cam on the lid's hinge, so the motions of the keyboard parts are always synchronized with the movement of the lid.

The unusual design is being displayed in the design collection of the Museum of Modern Art in Manhattan, New York.

所謂的「蝶型鍵盤」即是將較大的鍵盤分割成兩個很像三角型的小鍵盤，並且在電腦蓋子打開、關上時，籍由滑動來重新組合。
當蓋子打開時，兩個小鍵盤會向兩邊滑動，接著，一個小鍵盤再向下滑動，兩個小鍵盤就像「拼圖」一樣的重新組合成一個寬29.2公分(11.5英吋)的鍵盤並且超出電腦的機身。相反的，當蓋子合上時，一個小鍵盤會向(上)後滑動，接著兩個小鍵盤再滑向內側，直到電腦可以蓋上。整個動作是籍由安裝在電腦蓋子上的齒輪樞紐來驅動，所以，當電腦打開時，這整個動作(蝶型鍵盤的開合)永遠會同時執行。

這個相當特別的設計已經被展示在紐約曼哈頓的現代藝術博物館裡。
