Just for the record, there's no universal "standard layout", even if you're from the US (because, you know, there's a world outside USA).
I could probably search through the wiki to some explanation on layouts, but roughly, that's how it is:
- ANSI - 104 keys for full keyboard / US mostly, dunno which others countries use it
- ISO - 105 keys for full keyboard / Most of ISO-using countries have their own specific layouts, be it for accents, supernumerary characters...
I'll grant you that having so many "standards" on ISO is a pain, moreso when some countries (Germany) have way more models available than others (France, heh).
That's missing details, but hey, said it was rough :smile:
