QWERTY - the symbolic name of the alphabet letters on the keypad of the basic typewriter and a computer taken from the first six letters in the number of digits in a row, from left.
The first typewriters were used alphabetic set of keys. However, with rapid typing of frequently used keys to the neighborhood resulted in a mutual arms stuck in the font. In 1878 r.opatentowano first typewriter with the QWERTY key layout.
Such a system font is more effective than alphabetical. Although untrained individuals is difficult to remember the arrangement of letters and does not give the optimal speed of writing, has become the standard keyboard layout in modern devices.
But this is not the system that guarantees the fastest possible pace of writing. There are other ways of distribution of keys (for example, Dvorak keyboard), whose layout has been optimized in terms of speed of character input, not to avoid jamming of fonts (which does not occur such as computer keyboards). In these keyboards, the most common signs are placed at each side by side, which reduces the path we have to overcome your fingers when writing.
For each language layouts are slightly different. This is due to additional, specific to a given language diacritics. In Poland, the keyboard layout that allows additional Polish characters is called a keyboard programmer (as opposed to the typist keyboard layout based on QWERTY). Polish diacritical marks (A, C, E, L, N, O, t, Z, Z) is obtained mostly by simultaneously pressing the "Alt" and letter-like character (such as é are obtained with a combination of Alt e) . The exception is the letter "Z", which is achieved by simultaneously pressing the Alt and x (as a combination of Alt and yields desired). In computers, Apple Macintosh letter Z and Z are swapped [1], ie Option + Z gave ¬, and Option + X Ż. Since Mac OS X 10.5 Leopard, the system is the same as in devices from other manufacturers.
The system programmer is used outside the Polish and the Czech Republic and Romania, the Romanian system programmer is more similar to Polish.
Czech diacritical marks (á, C, E, E, I, R, S, u, u, y, z) is obtained by simultaneously pressing the Alt key (or AltGr) and the corresponding keys such as 8, 4, 2, 0 , 9, 5, 3,,, [, 7, 6
Romanian diacritics (â, t, i, a, s) is obtained by simultaneously pressing the Alt key (or AltGr) and Latin letters, which derives an additional Romanian character.
