民國初年, 鑒於中文查字困難, 陳立夫先生發明五筆檢字法,
以首四筆,末一筆的簡單方法從字典中找字. 可惜早了幾十年,
敵不過根深蒂固的 "字根部位法".
結果像我這樣的笨人都只好使用 "數筆畫表", 或 "難字表" 來找字.
除了 "木", "三點水", "火", .... 幾個簡單的部首,
好多字根本不知道從那裡查起!

你知道 "愛" 要查 "心" 部嗎?

1991 年, 北京商務出版張椿兄的 "新華字典 - 筆順部首檢字表",
張先生於 1980 年代提出:

橫 ( - ),
直 ( | ),
撇 (飄) ( / ),
點 ( . ),
曲 (乙)

五種基本筆畫.

檢字法總算向前跨了一步. 他捨棄 "部首" 不管,
專注意餘下的 "半字", 用他的 五種筆畫 分類去找字.
這樣查字典找字, 是簡單快速了許多.

最有效率的辦法是 "分類, 按序縮小範圍去找",
西方文字就是使用這種方法.

連幼稚園的小朋友都會查字典.

Abstract:

A system includes a keyboard for encoding Chinese characters and phrases. The invention relates to the quick input of Chinese characters and phrases into any large, medium, small and mini-sized computers as well as systems for Chinese information processing and communications. Some basic roots are selected according to their frequency distributions both in the constitution of characters and in practical usage, and classified in accordance with their inner links and compatible relations. These selected roots are then arranged on the twenty five keys of a standard keyboard in accordance with the probabilities of use of keys and the fingering of the keyboard in order to form a complete encoding system and a keyboard for Chinese. In the system, Chinese characters and phrases can be encoded according to their geometrical forms. Therefore the method is direct and easy to learn and convenient for touch typing, and the efficiency of input Chinese characters and phrases can be raised greatly.
