Numeric Keypads}} This grouping allows quick number entry with the right hand, without the need to use both hands on number row of main keyboard. On a standard [IBM PC keyboard](/source/IBM_PC_keyboard), numpad has 17 keys, including digits {{key press|0}} to {{key press|9}}, {{key press|+}} ([addition](/source/addition)), {{key press|-}} ([subtraction](/source/subtraction)), {{key press|*}} ([multiplication](/source/multiplication)), and {{key press|/}} ([division](/source/Division_(mathematics))) symbols, {{key press|.}} ([decimal point](/source/decimal_point)), {{key press|[Num Lock](/source/Num_Lock)}}, and {{key top|Enter}} keys.''[http://foldoc.org/Numeric+keypad numeric keypad]'' at [FOLDOC](/source/FOLDOC) On smaller keyboards (such as those found on [laptop](/source/laptop)s{{Cite web |title=Enable or Disable Numpad on Laptop Keyboard |url=https://smittystips.com/pctips/v_enable_laptop_numpad.php |access-date=2025-06-06 |website=smittystips.com}}), the numeric keypad can be implemented as alternative markings on alphabetic keys (usually {{key press|I}}-{{key press|O}}-{{key press|P}}, {{key press|K}}-{{key press|L}}-{{key press|;}}, {{key press|,}}-{{key press|.}}-{{key press|/}}) or added as a separate unit, that can be connected to a device by means such as [USB](/source/USB); some of these may include keys not found on a standard numpad, such as a [spacebar](/source/spacebar) or a {{key press|00}} (or {{key press|000}}) key. Sometimes it is necessary to distinguish between a key on the numpad and an equivalent key elsewhere on the keyboard. For example, depending on the [software](/source/software) in use,{{efn|E.g. [Blender](/source/Blender_(software)) makes specific use of numpad keys for several [keyboard shortcuts](/source/keyboard_shortcuts).}} pressing the numpad's {{key press|0}} key may produce different results than pressing the [alphanumeric](/source/Computer_keyboard) {{key press|0}} key.{{efn|I.e. the {{key press|0}} key above the letter keys and to the right of the {{key press|9}} key on a typical [QWERTY](/source/QWERTY) keyboard.}} In such cases, the numpad-specific key may be indicated as e.g. {{key press|Numpad 0}}, {{key press|NumPad0}},{{efn|E.g. as defined in [C#](/source/C_Sharp_(programming_language))'s System.ConsoleKey [enumeration](/source/Enumerated_type): {{cite web |title=mscorlib/system/consolekey.cs |url=https://github.com/microsoft/referencesource/blob/e0bf122d0e52a42688b92bb4be2cfd66ca3c2f07/mscorlib/system/consolekey.cs#L106-L121 |website=Microsoft/ReferenceSource repository |at=At line 106 |publisher=[GitHub](/source/GitHub) |author=Microsoft |author-link=Microsoft |access-date=24 June 2019 |date=23 May 2019 |orig-year=2014}} NumPad0 = 0x60, NumPad1 = 0x61, NumPad2 = 0x62, NumPad3 = 0x63, ... }} {{key press|Num 0}}, or likewise to remove ambiguity. Numeric keypads usually operate in two modes. When {{key press|Num Lock}} is off, keys {{key press|8}}, {{key press|6}}, {{key press|2}}, and {{key press|4}} act like arrow/navigation keys up, right, down, and left; and {{key press|7}}, {{key press|9}}, {{key press|3}}, and {{key press|1}} act like {{key press|[Home](/source/Home_key)}}, {{key press|[PgUp](/source/Page_Up_and_Page_Down_keys)}}, {{key press|[PgDn](/source/Page_Up_and_Page_Down_keys)}}, and {{key press|[End](/source/End_key)}}, respectively. With {{key press|Num Lock}} on, digit keys produce the corresponding digit. On [Apple](/source/Apple_Inc.) [Macintosh](/source/Macintosh) computers, which lack a {{key press|Num Lock}} key, the numeric keypad always produces only numbers; the {{key press|Num Lock}} key is replaced by the {{key press|[Clear](/source/Clear_key)}} key. The arrangement of digits on numeric keypads with the {{key press|7}}-{{key press|8}}-{{key press|9}} keys two rows above the {{key press|1}}-{{key press|2}}-{{key press|3}} keys is derived from [calculator](/source/calculator)s and [cash register](/source/cash_register)s. It is notably different from the layout of [telephone Touch-Tone keypads](/source/Telephone_keypad) which have the {{key press|1}}-{{key press|2}}-{{key press|3}} keys on top and {{key press|7}}-{{key press|8}}-{{key press|9}} keys on the third row. Numeric keypads are useful for entering long sequences of numbers quickly, such as in [spreadsheet](/source/spreadsheet)s, financial/accounting programs, and calculators. Input in this style is similar to a calculator or [adding machine](/source/adding_machine). A numeric keypad is also useful on [Windows](/source/Microsoft_Windows) [PCs](/source/Personal_computer) for typing [alt code](/source/alt_code)s for special symbols; for example, the degree symbol, °, can be typed on these computers with the sequence {{key press|chain=+|Alt|0|1|7|6}}.{{Cite web |title=Degree Symbol |url=https://www.degreesymbol.net/ |access-date=2025-01-22 |website=www.degreesymbol.net |language=en}} To maintain their compact size, most laptops do not include a numeric keypad on their keyboard (though they can sometimes be found on larger models); even some desktop keyboards designed for compactness omit a numpad. To compensate, most such keyboards include {{Key press|Num Lock}} integrated into a function key (typically {{Key press|F6}} or {{Key press|F8}}) and then press keys like {{Key press|7}} to produce their numpad counterpart. == Chinese input methods == The numeric keypad is used by some [systems for input of Chinese characters](/source/Chinese_input_methods_for_computers), for example [CKC Chinese Input System](/source/CKC_Chinese_Input_System) and [Q9 input method](/source/Q9_input_method). == Computer games and mousing alternative== [[Image:Qwerty.svg|thumb|right|450px|A 104-key PC [US](/source/United_States) [English](/source/English_language) [QWERTY](/source/QWERTY) keyboard layout with the '''numeric keypad''' at the far right]] Numeric keypads are also used for playing some older [computer game](/source/computer_game)s where the player must control a character, such as [roguelike](/source/roguelike)s and ''[Sid Meier's Pirates!](/source/Sid_Meier's_Pirates!)''. For keyboards without a numeric keypad, some games provide alternative movement keys, such as classic ''[Rogue](/source/Rogue_(computer_game))'s'' [HJKL keys](/source/HJKL_keys). The numeric keypad can also be an alternative to the [WASD](/source/Arrow_keys) keys for navigation in computer gaming. This can be an attractive option for [left-handed](/source/left-handed) people who prefer to use the [mouse](/source/Mouse_(computing)) with their left hand. Most [operating system](/source/operating_system)s have a [mouse keys](/source/mouse_keys) [accessibility](/source/Computer_accessibility) feature where mouse navigation can be done using the numeric keypad, with the other keys adapted to be [mouse button](/source/mouse_button)s. == See also == * [Alphonse Chapanis](/source/Alphonse_Chapanis) * [Gaming keypad](/source/Gaming_keypad) * [Keypad](/source/Keypad) == Notes == {{notelist}} == References == {{reflist}} {{Commons category|Numeric keypads}} {{keyboard}} {{keyboard keys}} {{DEFAULTSORT:Numeric Keypad}} Category:Computer keys Category:Japanese inventions --- Adapted from the Wikipedia article [Numeric keypad](https://en.wikipedia.org/wiki/Numeric_keypad) by Wikipedia contributors ([contributor history](https://en.wikipedia.org/wiki/Numeric_keypad?action=history)).
