There are a variety of layouts that, for the most part, follow the phonology of the letters on a Latin-character keyboard such as the QWERTY or AZERTY. Where no phonology mapping is possible, or where multiple Hebrew letters map to a single Latin letter, a similarity in shape or other characteristic may be chosen. For instance, if ס ("samech") is assigned to the S key, ש (shin/sin) may be assigned to the W key, which it arguably resembles. The shift key is

Principles commonly used in their design include maximising use of the home row, minimising finger movement, maximising hand alternation or inward rolls (where successive letters are typed moving towards the centre of the keyboard), minimising changes from QWERTY to ease the learning curve, and so on. Maltron also has a single-handed keyboard layout. Programs such as the Microsoft Keyboard
