Keyboard layouts are arranged non-alphabetically, and this can be attributed to historical and practical reasons. The design of modern keyboards can be traced back to the typewriter, which Christopher Latham Sholes invented in the 1860s. The typewriter’s key layout was specifically devised to prevent mechanical arms with typefaces from jamming during fast typing.
Initially, a major issue with typewriters was the tangling and jamming of mechanical arms when users typed rapidly. To address this concern, Sholes reorganized the keys to slow down typing speed and reduce the likelihood of jamming. Hence, it was the birth of the QWERTY layout.
The QWERTY layout, still widely utilized on most keyboards today, strategically positions the most frequently used letters in hard-to-reach spots to slow down typing speed. This design was based on the frequency of letter combinations in the English language, to minimize the occurrence of mechanical arm jams.
Despite the development of various keyboard layouts over time, the QWERTY layout has remained predominant due to its user familiarity and extensive adoption. Moreover, changing the key arrangement would necessitate users to relearn typing, causing significant inconvenience.
In recent years, alternative keyboard layouts like the Dvorak Simplified Keyboard and Colemak have been created. These layouts are designed for enhanced efficiency and ergonomics compared to QWERTY. However, their widespread adoption has been limited due to the substantial learning curve required to transition to a new layout.
