Due to the concise coding rules of traditional two-stroke brushstrokes and the inventor's open attitude towards holding patents, a group of improved two-stroke brushstrokes enthusiasts who are committed to optimizing the traditional two-stroke brushstrokes coding have been born. They have made some modifications or rearranged the key positions of two strokes on the basis of the traditional coding rules of two strokes. After more than ten years of development, Bi Er has many different versions, which are maintained by many Bi Er fans.
According to the number of coded keys, it can be divided into:
30-key two-stroke: original two-stroke (including Song Qing two-stroke and pure two-stroke), super two-stroke and Pentium two-stroke etc.
28 keys and two strokes: two strokes in the cloud, etc. ;
27 keys and two strokes: idle cloud fast code, etc.
26-key two strokes: free two strokes, super sound shape, rabbit two strokes, zhe dou sound shape code, leap two strokes, etc.
25 keys and two strokes: Chinese block spelling, Chinese block spelling and Chinese block spelling, in which Chinese block is two strokes based on form;
According to the coding type, it can be generally divided into three categories:
Original two-stroke code: original two-stroke code (including Song Qing's two-stroke code and pure two-stroke code), idle cloud fast code, leap two-stroke code and so on.
Super size two: Super size two, Supersonic shape, Free size two, Walking size two, Zhe Zhe Dou Phonetic shape code, Rabbit size two, etc.
Other coding types: Chinese series input method, etc.
In the two-stroke input method, Song Qing's two strokes and pure two strokes belong to the original two strokes, not a new two-stroke type. The key position distribution and code selection principles of these two strokes are exactly the same as those of the original two strokes.
In the original two strokes, fault-tolerant coding is set for some Chinese characters with split ambiguity. For example, the word "Li" is a combination of upper and lower structures, and the correct coding is "LZGU", but some people think that this word is a single word, so the fault-tolerant coding is "LJ". X "is given in the original two strokes, but these fault-tolerant codes are no longer kept in the pure two strokes, and the codes are taken in strict accordance with the laws of Chinese characters and the stroke order norms promulgated by the Ministry of Education.
Song Qing, also known as Biao Bian, not only strictly abides by the original standards, but also adopts a fault-tolerant code that divides into two for Chinese characters such as "you" and "Zhu". In addition, Song Qingbier also uses UV key equalization to set simplified fault-tolerant coding.
In view of the difficulty in getting the code of the third and fourth strokes of the original two strokes, the code of the third and fourth strokes was cancelled by Chaoer Pen, and the following improvements were made:
Taking the last stroke as three yards, the last stroke is intuitive and easier to master;
The combined Chinese characters are all yin and yang, which can avoid splitting and combining the strokes of two whole parts into two strokes, and the word separation is more intuitive.
