Raised marker on 5
The article does not mention the raised bar on the "5" button, it has a raised bar just like the "F" and "J" button does. --anonymous (talkpage history lost?)


 * My HP keyboard has a raised dot on the "5" button, whereas the "F" and "J" have a bar. --202.77.13.1 09:05, 28 November 2006 (UTC)

"Ten-Key" keyboard
What's the difference between an numpad and a "Ten-Key" keyboard. No where on Wikipedia is there information on this. Perhaps they are the same thing. If so, this could be an "also known as". PS: The adding machine page also doesn't mention "ten-key". --anonymous (talkpage history lost?)

Merge?

 * Numpad should be worth of its own article. Some applications such as bank teller computers even have a splitted numpad for easy typing.--202.77.13.1 09:03, 28 November 2006 (UTC)
 * I don't think this merge is warranted. We have separate articles about every part of computer keyboard and keypad is a different thing entirely.  Grue   14:30, 30 November 2006 (UTC)
 * I concur, the article has its own merits. I do think it could be expanded some, though. For instance, what are the origins of the arrangement of 7 8 9, 4 5 6, and 1 2 3? fury 22:54, 15 January 2007 (UTC)
 * I feel a numeric keypad is specific to a computer keyboard, and is worth its own little article. Keypads cover all sorts of other devices - telephone keypads, calculators, door entry systems... Davidbod 23:40, 30 January 2007 (UTC)
 * Just added mention of use of the numpad in some Chinese input methods for computers. Would seem to be another reason to keep this separate article. --A12n 12:22, 3 May 2007 (UTC)
 * The merge template has been up since April, but everyone who has discussed it here or on Talk:Keypad is opposed to the merge. I think it's time to remove the template. ~Inkington 17:31, 15 August 2007 (UTC)

Calculator keypad layout
I searched for "numpad" on wikipedia to find out why the 123 and 789 keys are placed different from the way they are on for example a phone, but this is not mentioned. Nor is it mentioned on the "keypad" page. I believe I'm not the only one interested in knowing why this is so. I will look for the answer elsewere and if I find it I'll add it to the article. If someone else knows/finds it first, please be so kind as to add it yourself. Manos1394

According to the article: However, the arrangement of the numbers is similar to that on the keyboards of calculators. This is not true, calculators come in both flavors. Removing that sentence (it doesn't add much anyways ;-) Jaho (talk) 14:15, 28 March 2010 (UTC)

Anyone have an explanation why 1-2-3 is on the bottom and 7-8-9 in the top? I think the "phone layout" is much more intuitive and ergonomically more valid. Maybe something to do with adding machines and cash registers using columns of 1 to 9 with the 1 on the bottom? --BjKa (talk) 12:32, 20 May 2015 (UTC)


 * I was with HP when the HP35 came about, worked at Page Mill Road, and I remember the time when rotary dials were replaced by pushbuttons. We always had long discussions which way to layout the block. Old (electro-)mechanic calculators and even modern ones have 123 at the bottom, below often 0, 00, 000, or 0, 00, decimal point or comma. Phones started with 123 at the top, as "normal" people were to use them, not just office clerks. (Sweden started the rotary dial with 0 instead of 1, so all international DDD had to regenerate the dial’s impulses.) And then there was an even longer discussion how to standardize the letters onto the number keys of the touchtone phones, as rotarys had different setups in London and New York .

One more photo?
Does anybody have a photo of a keyboard without numeric keypad with the 6 buttons in a 3x2 block: and the following 4 below:

I could not find any in the WWW. Q0k (talk) 06:46, 14 September 2009 (UTC)

number pad 5 with num lock off
Is any signal sent to the computer when 5 is pressed without num lock on? — Preceding unsigned comment added by 2602:252:D79:2010:6520:DBCF:313:7D0A (talk) 21:47, 27 November 2015 (UTC)

Yes, I just checked and my keyboard sends key code 84 which is being recognized as KP_Begin. I don't know what is a Begin key, but apparently it exists. It is listed here: http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/key-names.html and Emacs' manual mentions it in the "Other cursor repositioning keys" section, so I guess it has something to do with moving the text cursor: https://www.gnu.org/software/emacs/manual/html_node/emacs/Function-Keys.html but I can't find what exactly does it do, it doesn't seem to do anything in a text editor (gedit), nor in a Linux console.

Too specific to computers
Numeric keypads positioned to the right of a standard typewriter keyboard date back to the mid 1960s. Specifically, the Singer/Friden 2210/2211 Flexowriter had one. See the photo and caption here. This was definitely not a computer keyboard, but rather, an electric typewriter with attached paper-tape reader and punch. Yes it was used with computers, but it could also operate as a stand-alone word processor. Douglas W. Jones (talk) 21:28, 21 June 2016 (UTC)

ATM Machines
Wikipedia readers likely come across fewer computer keypads, if at all, than ATM machine keypads. It should be mentioned what is the likely ATM arrangement of numbers. Theking2 (talk) 15:33, 10 April 2021 (UTC)
