Hebrew keyboard key (or pressing Caps Lock) in Windows produces the uppercase Latin letter without the need to switch layouts. 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
QWERTY with a US-style keyboard in all versions of Windows prior to Vista through the use of the AltGr key modifier. MS Windows 7 now includes the correct diacritical signs in the default Romanian Keyboard layout. This layout has the Z and Y keys mapped like in English layouts and also includes characters like the 'at' (@) and dollar ($) signs, among others. The older cedilla-version layout is still included albeit as the 'Legacy' layout. In Slovakia, similarly to the Czech Republic, both QWERTZ and QWERTY keyboard layouts are used. QWERTZ is the default keyboard layout for Slovak in Microsoft Windows.
