Common keys on keyboards around the world

Recommended Posts

I would like to know what are common keys on keyboards around the world. My aim is to focus user interface development based on common keys. My first guess would be: - Function keys from F1 to F10 - Ctrl, Alt, Space, Return, Escape, Shift - Numeric Keypad 0-9 with operators (/*-+), decimal separator and return key Does anybody know ?

Keyboards for languages which don't use the Roman alphabet generally have it available on the keys anyway, simply because the entire world uses ASCII. So using letters is probably fine.

Those keys are not available on a few small keyboards and not so easily accessible on laptop keyboards.

For what it's worth, Up, Down, Left, Right, Home, End, Page Up, Page Down, Insert and Delete are relatively standard keys (as part of the number pad on 84 key keyboards). On 102 (101) key keyboards they appear as their own group, with the E0 modifier sent along with their usual scancode.

@Sneftel:
I have searched the net for pictures of Japanese/Chinese keyboards. Eventhough they both have their native alphabet and the roman one, users typing characters use key combination to modify the final character appearance in their native language (from what I read regarding the use of those keyboards). I also have found hindi keyboard pictures with only the native displayed.

To my mind, this means that letters are not an option when a user uses a keyboard in its native configuration:
- I do not know if these keyboards use the same scan codes regarding the way characters typed are interpreted,
- the wrappers I use may not even return the correct key since they are either based on ASCII or ISO 8859 roman standards.

@benryves:
I have not considered small keyboards: the only example I had was a keyboard for disabled persons with only a valid left hand. There is no numeric keypad, the common keys are:
- function keys from F1 to F10
- Return, space, insert, del, home, end, page up, page down.
- Directional keys
Regarding notebooks, I thought that people would have before long added a numeric keypad with a mouse. Maybe I am just plain wrong.

@all:
for curiosity sake, I found this site which shows a lot of keyboard layouts and explains some input mecanisms behind these keyboards.
