The most efficient typing layout is generally considered to be "QWERTY," which is the most commonly used keyboard layout in the English-speaking world. "QWERTY" was developed in the 1870s to minimize key jams on mechanical typewriters. The layout arranges frequently used letters in a way that requires the least hand and finger movement, leading to faster typing speeds and higher accuracy. Alternative keyboard layouts, such as "Dvorak Simplified Keyboard" and "Colemak Keyboard," have been designed to improve typing efficiency by placing commonly used letters in the home row and reducing finger movement. These layouts can increase typing speed and reduce typing-related injuries. However, they are not as widely used as "QWERTY."
