Alt code
open-in-new
<h2 id="ms-dos">MS-DOS</h2> <p>On <a href="/facts/IBM_PC_compatible/zGUpl7Sh">IBM PC compatible</a> <a href="/facts/Personal_computer/koaYfNce">personal computers</a> from the 1980s, the <a href="/facts/BIOS/2RY3dzQe">BIOS</a> allowed the user to hold down the Alt key and type a decimal number on the keypad. It would place the corresponding code into the keyboard buffer so that it would look (almost) as if the code had been entered by a single keystroke. Applications reading keystrokes from the BIOS would behave according to what action they associate with that code. Some would interpret the code as a command, but often it would be interpreted as an 8-bit character from the current <a href="/facts/Code_page/tgcBrILG">code page</a> that was inserted into the text the user was typing.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> On the original <a href="/facts/IBM_PC/yhcJGMPL">IBM PC</a> the code page was <a href="/facts/CP437/jx27vCbb">CP437</a>. </p><p>Some Eastern European, Arabic and Asian computers used other hardware <a href="/facts/Code_page/tgcBrILG">code pages</a>, and MS-DOS was able to switch between them at runtime with commands like KEYB, <a href="/facts/List_of_DOS_commands/d72UqhJ3">CHCP</a> or <a href="/facts/List_of_DOS_commands/d72UqhJ3">MODE</a>. This causes the Alt combinations to produce different characters (as well as changing the display of any previously-entered text in the same manner). A common choice in locales using variants of the Latin alphabet was <a href="/facts/CP850/D7wzDcLh">CP850</a>, which provided more Latin character variants. (There were, however, many more code pages; for a more complete list, see <a href="/facts/Code_page/tgcBrILG">code page</a>). </p><p>PC keyboards designed for non-English use included other methods of inserting these characters, such as national <a href="/facts/Keyboard_layout/6aYkBXuK">keyboard layouts</a>, the <a href="/facts/AltGr_key/krEsBUjB">AltGr key</a> or <a href="/facts/Dead_key/5jlo4RW5">dead keys</a>, but the Alt key was the only method of inserting some characters, and the only method that was the same on all machines, so it remained very popular.[<i>where?</i>] This input method is emulated by many pieces of software (such as later versions of MS-DOS and Windows) that do not use the BIOS keyboard decoding. </p><p>In the ASCII standard, the numbers 0-31 and 127 are assigned to <a href="/facts/Control_character/jkWgHvfC">control characters</a>, for instance, <a href="/facts/Code_point/R184ugJX">code point</a> 7 is typed by Ctrl+G. While some (most?) applications would insert a <a href="/facts/Bullet_(typography)/DyPRSa50">bullet</a> character • (code point 7 on <a href="/facts/Code_page_437/jx27vCbb">code page 437</a>), some would treat this identical to Ctrl+G which often was a command for the program. </p> <h2 id="windows">Windows</h2> <p>The Alt codes had become so well known and memorized by users that Microsoft decided to preserve them in <a href="/facts/Microsoft_Windows/bwhAhuSL">Microsoft Windows</a>, even though the OS features a newer and different set of "<a href="/facts/Windows_code_page/YKreB8a3">ANSI code pages</a>", such as <a href="/facts/CP1252/eyM337y0">CP1252</a>. Windows includes the following processing algorithm for Alt code, which supports both methods: </p> <ul><li>The familiar Alt+### combination retains the old <a href="/facts/MS-DOS/fVrrz1uN">MS-DOS</a> behavior, i.e., generates characters from the legacy code pages now called "<a href="/facts/Windows_code_page/YKreB8a3">OEM code pages</a>".<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a></li></ul> <ul><li>The new Alt+0### combination (which prefixes a zero to each Alt code), produces characters from the newer "<a href="/facts/Windows_code_page/YKreB8a3">ANSI code pages</a>".<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a><a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a></li></ul> <p>Users could modify both active system code pages via `intl.cpl` > `Administrative` > `Change system locale`, which would result in different characters being produced when entering Alt codes.<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> </p><p>For example, if the "English (United States)" locale is selected in Windows, then Alt+163 produces U+00FA ú LATIN SMALL LETTER U WITH ACUTE, which corresponds to code point 163 in the <a href="/facts/Windows_code_page/YKreB8a3">OEM code page</a> <a href="/facts/CP437/jx27vCbb">CP437</a>. In contrast, for the "Russian (Russia)" locale, the same input yields U+0436 ж CYRILLIC SMALL LETTER ZHE from <a href="/facts/CP866/EVzFRhhH">CP866</a>. </p><p>Using the zero-prefixed Alt code, if the "English (United States)" locale is selected, then Alt+0163 results in U+00A3 £ POUND SIGN, which occupies position 163 in the <a href="/facts/Windows_code_page/YKreB8a3">ANSI code pages</a> <a href="/facts/CP1252/eyM337y0">CP1252</a>. For the "Russian (Russia)" locale, however, the same input yields U+0408 Ј CYRILLIC CAPITAL LETTER JE from <a href="/facts/CP1251/mb3epF8S">CP1251</a>. </p> <h2 id="unicode">Unicode</h2> <p>Later versions of Windows and applications such as Microsoft Word supported Unicode. As Unicode included all the characters in the MSDOS code pages, this had the immediate benefit that all the old MSDOS Alt combinations worked, not just the ones that existed in the Windows Code Page. </p><p>In the IBM PC Bios typing an Alt code greater than 255 produced the same as that number <a href="/facts/Modulo_operator/V5xPUluD">modulo</a> 256.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> Some applications retained this behavior, while others (in particular applications using the Windows <a href="/facts/RichEdit/NLpqhjPz">RichEdit</a> control, such as <a href="/facts/WordPad/68Dx4WF7">WordPad</a> and <a href="/facts/PSPad/0gh05rrr">PSPad</a>) made numbers from 256 to 65,535 produce the corresponding Unicode character.<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> For instance, Alt+9731 in WordPad produces the U+2603 ☃ SNOWMAN. If the Windows Code Page was set to CP1252 then all Unicode characters except <a href="/facts/C0_and_C1_control_codes/bBp1dGVl">control characters</a> could be typed this way. </p> <h3>Alternatives</h3> <p>Because most Unicode documentation and character tables show the code points in <a href="/facts/Base_16/02ohQW22">hex</a>, not decimal, a variation of Alt codes was developed to allow the typing of numbers in hex (using the main keyboard for A–F). To enable it, a user must set or create a string type (REG_SZ) value called EnableHexNumpad in the <a href="/facts/Windows_Registry/cH9RlHTp">registry</a> key HKEY_CURRENT_USER\Control Panel\Input Method, assign the value data 1 to it, and then reboot or log out/in. A leading + then indicates hex input, for example Alt++11B will produce ě (e with <a href="/facts/Caron/NSslRDsj">caron</a>). </p><p>There are many <a href="/facts/Unicode_input/oazW5Abx">other ways</a> of typing arbitrary Unicode characters, such as the <a href="/facts/Character_Map_(Windows)/MBR5FvWf">Character Map</a> utility. </p> <h2 id="other-operating-systems">Other operating systems</h2> <p>The Alt key method does not work on <a href="/facts/ChromeOS/zH0B5Xtk">ChromeOS</a>, <a href="/facts/MacOS/Y93vVpTm">macOS</a>, <a href="/facts/Linux/9FvCKSTq">Linux</a> or other <a href="/facts/Operating_system/8XTuvMh2">operating systems</a> and there is no evidence of interest in replicating it. However, numeric entry of Unicode characters is possible in most <a href="/facts/Unix/0pNL2seI">Unix</a> or <a href="/facts/Unix-like/YAKrAxzd">Unix-like</a> OSs by pressing and releasing Ctrl+⇧ Shift+U, and typing the hex number followed by the space bar or enter key. For example, </p> <ul><li>For the <a href="/facts/Registered_trademark_symbol/lLGeMyUG">registered trademark symbol</a> ®, type Ctrl+⇧ Shift+U, AE, ↵ Enter.</li> <li>For the <a href="/facts/One-way_traffic/WpXIG0BB">no entry sign</a> ⛔, type Ctrl+⇧ Shift+U, 26D4, ↵ Enter.</li></ul> <h2 id="limitations">Limitations</h2> <p>If <a href="/facts/Num_lock/xISJyA7h">Num lock</a> is disabled, attempting an Alt code may cause unexpected results in some applications, due to the controls used on the same key. For example, Alt+4 can be taken as Alt+←, causing a web browser to go back one page. </p> <h2 id="list-of-codes">List of codes</h2> <table><tbody><tr><th
