QWERTYUIOP

QWERTYUIOP is the sequence of ten letters that makes up the top row of letters on standard QWERTY keyboards: Q, W, E, R, T, Y, U, I, O, P.

The arrangement is part of the QWERTY layout, designed in the 1870s by Christopher Latham Sholes for typewriters. The purpose was to reduce mechanical jams by spacing frequently used letters and balancing typing speed across the row, a design that later became the basis for the most common keyboard layout used in English-language computing.

On modern keyboards, these keys are typically typed with the left hand handling Q, W, E, R, and T and the right hand handling Y, U, I, O, and P, reflecting their positions along the top row. The string QWERTYUIOP is sometimes used as a quick demonstration of the upper-row typing pattern or as a simple test string in keyboards and software.

Other keyboard layouts, such as AZERTY and DVORAK, place different letters on the top row, so the exact sequence QWERTYUIOP is not universal. The term is most closely associated with the QWERTY standard widely used in many regions, and it is often encountered in discussions of keyboard design and typing practice.
