Why There is 12 Function key on Key board? [modified]
-
Do any one know the philosophy of existing 12 function key F1-F12 on key board? why it is not 14 or 10? I searched and found it was 24 at first and Over time it reduced and now is 12. But Not Convinced, yet! Any Story or Reason?? :confused::confused:

Arbitrary. My LK201 has F1 through F20, plus PF1 through PF4. :-D
What do you use the Compose key for now then ?

I personally think the keys should start at F0 instead of F1.

Maybe we should go back to 24 keys, but use letters instead of numbers... FA, FB, FC, FD... And the-key-formerly-known-as-F21 should be a shortcut for Kill Process.

*shrugs* dunno. My first computer was a C64 with 8 function keys though. After that I had an Amiga which had 10 (though it did have separate dedicated keys for "Help" and maybe a few other things). My latest keyboard (which I can't currently use due to driver issues and think I need to reinstall windows to get the damn thing working) has 24 - F1 to F12 and G1 to G12. Though the G keys are programmable macro ones which I've never really found a use for.

On the keyboard I'm using, there is room over the backspace key for a 13th F key, even with the little gap that separates every fourth key.

On the earliest computer keyboards, there were no dedicated function keys. Instead, you had a
Fnbutton which, when used with the number row keys, had special meaning. Some laptop computers continue to use this arrangement today. The next step was to expand the keyboards to eliminate theFnkey and add dedicated function buttons. Because of their being ten numbers, there were ten function keys. In later designs, keyboards typically had 14 keys in the top row: the backtick, one through zero, bottom dash, equals, and backspace. Briefly, keyboards had 14 function keys, one above each of the keys in the regular top row. Having theEsckey in the top left became common and eventually the standard, replacing the left-most function key. Rather than have 13 function keys and scaring off a lot of superstitious ninnies, the number was reduced to 12. This also added a bit of space to offset the function keys, making them a bit easier to use quickly. -

Fn) similar toCtrlorAlt.Fnwas used with the number keys, which have always been layed out 1 to 0. So when dedicated function keys were added to keyboards, they kept the same arrangement with F1 on the left, then F2, F3 and so on. Having F0 as the right most looked funny, so it came to be labeled as F10. -

why 10 why not 9?
10 is a nice round number and one that naturally occurs to designers/technicians because of its association with the decimal base. So they automatically chose it over arbitrary numbers like 9 or 11. Later they tried to squeeze in 2 more and got 12. 14 would have been nice but it would have crowded the keyboard layout. These days it does not matter much.

It does F0 is Esc. :-D

10 also fit naturally with the function keys on the side layout since a standard keyboard has 5 rows of keys.
3x12=36 2x12=24 1x12=12 0x12=18
And so it was with the original IBM XT: http://en.wikipedia.org/wiki/File:Ibm_px_xt_color.jpg[^] 83 keys, 10 of them function keys.

Before there were PCs with keyboards, there were video terminals with keyboards. A lot of them that I remember had function keys on them. Most of the early VT, Wyse and even IBM terminals that I used to work with invariably had at least 10 function keys on them. :)
