Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. International QWERTY keyboards feature minor changes to the QWERTY key layout used on most computer keyboards. Belgian and French keyboards interchange both Q and W with A and Z and move M to the right of L; they are known as AZERTY keyboards. However, the French Canadian layout is a QWERTY layout. Czech keyboards use QWERTZ keyboards. They exchange the Z and Y like the German one, yet uses a "krou¿ek" u (¿) to the right of L and (ú) next to P. The row which is normally reserved for numerals in other layouts is used to produce the diacritics ¿, ¿, ¿, ¿, ¿, ý, á, í, é. The shift key is used to create numerals in this system. Uppercase diacritics are found, using a word processor, by holding shift, keying the equals sign and the related letter. Thus shift + =, shift + Z gives a ¿. Other punctuation marks and symbols also vary from the English version. There are also layout variants which are more or less close to the original US QWERTY layout; one of them puts Y and Z at their original positions, Czech - QWERTY.
