One popular but possibly apocryphal [2] :162 explanation for the QWERTY arrangement is that it was designed to reduce the likelihood of internal clashing of typebars by placing commonly used combinations of letters farther from each other inside the machine. [5] Differences from modern layout Substituting characters Christopher Latham Sholes's 1878 QWERTY keyboard layout Alternating hands while typing is a desirable trait in a keyboard design. While one hand types a letter, the other hand can prepare to type the next letter, making the process faster and more efficient. In the QWERTY layout many more words can be spelled using only the left hand than the right hand. In fact, thousands of English words can be spelled using only the left hand, while only a couple of hundred words can be typed using only the right hand [10] (the three most frequent letters in the English language, E T A, are all typed with the left hand). In addition, more typing strokes are done with the left hand in the QWERTY layout. This is helpful for left- handed people but disadvantageous for right-handed people.

The B00 key (left of Z), shifted, results in vertical bar | on some systems (e.g. Windows UK/Ireland keyboard layout and Linux/ X11 UK/Ireland keyboard layout), rather than the broken bar ¦ assigned by BS 4822 and provided in some systems (e.g. IBM OS/2 UK166 keyboard layout) From Windows XP SP2 onwards, Microsoft has included a variant of the British QWERTY keyboard (the "United Kingdom Extended" keyboard layout) that can additionally generate several diacritical marks. This supports input on a standard physical UK keyboard for many languages without changing positions of frequently used keys, which is useful when working with text in Welsh, Scots Gaelic and Irish — languages native to parts of the UK ( Wales, parts of Scotland and Northern Ireland respectively). Contrary to popular belief, the QWERTY layout was not designed to slow the typist down, [2] :162 but rather to speed up typing. Indeed, there is evidence that, aside from the issue of jamming, placing often-used keys farther apart increases typing speed, because it encourages alternation between the hands. [11] (On the other hand, in the German keyboard the Z has been moved between the T and the U to help type the frequent digraphs TZ and ZU in that language.) Almost every word in the English language contains at least one vowel letter, but on the QWERTY keyboard only the vowel letter A is on the home row, which requires the typist's fingers to leave the home row for most words. QWERTY was designed for English, a language with accents (' diacritics') appearing only in a few words of foreign origin. The standard US keyboard has no provision for these at all; the need was later met by the so-called " US-International" keyboard mapping, which uses " dead keys" to type accents without having to add more physical keys. (The same principle is used in the standard US keyboard layout for macOS, but in a different way). Most European (including UK) keyboards for PCs have an AltGr key ('Alternative Graphics' key, [a] replaces the right Alt key) that enables easy access to the most common diacritics used in the territory where sold. For example, default keyboard mapping for the UK/Ireland keyboard has the diacritics used in Irish but these are rarely printed on the keys; but to type the accents used in Welsh and Scots Gaelic requires the use of a " UK Extended" keyboard mapping and the dead key or compose key method. This arrangement applies to Windows, ChromeOS and Linux; macOS computers have different techniques. The US International and UK Extended mappings provide many of the diacritics needed for students of other European languages.Also, on MS Windows, the tilde character "~" ( ⇧ Shift+ `) acts as a dead key to type Polish letters (with diacritical marks) thus, to obtain an "Ł", one may press ⇧ Shift+ ` L. The tilde character is obtained with ⇧ Shift+ ` Space. It has been suggested that this section be split out into another article. ( Discuss) (October 2021) The cedilla-versions of the characters do not exist in the Romanian language (they came to be used due to a historic bug). [40] The UCS now says that encoding this was a mistake because it messed up Romanian data and the letters with cedilla and the letters with comma are the same letter with a different style. [41] In this layout, the grave accent key ( `¦) becomes, as it also does in the US International layout, a dead key modifying the character generated by the next key pressed. The apostrophe, double-quote, tilde and circumflex ( caret) keys are not changed, becoming dead keys only when 'shifted' with AltGr. Additional precomposed characters are also obtained by shifting the 'normal' key using the AltGr key. The extended keyboard is software installed from the Windows control panel, and the extended characters are not normally engraved on keyboards.

Two keyboard layout that are based on Qwerty are used in Arabic-speaking countries. Microsoft designate them as Arabic (101) and Arabic (102). The current Romanian National Standard SR 13392:2004 establishes two layouts for Romanian keyboards: a "primary" [37] one and a "secondary" [38] one.Multilingual keyboard layouts, unlike the default layouts supplied for one language and market, try to make it possible for the user to type in any of several languages using the same number of keys. Mostly this is done by adding a further virtual layer in addition to the ⇧ Shift-key by means of AltGr (or 'right Alt' reused as such), which contains a further repertoire of symbols and diacritics used by the desired languages. Further information: British and American keyboards United Kingdom and Ireland (except Mac) keyboard layout United Kingdom Keyboard layout for Linux Windows Vista and newer versions include the correct diacritical signs in the default Romanian Keyboard layout. English-speaking Canadians have traditionally used the same keyboard layout as in the United States, unless they are in a position where they have to write French on a regular basis. French-speaking Canadians respectively have favoured the Canadian French keyboard layout (see French (Canada), below).
