A) All the keycaps that include a secondary letter (A/Á, N/Ñ, P/Ö, Z/Æ etc.) should present the secondary letter in the upper right corner instead of the lower right. ALL the letters are wrong, except ß (which is lowercase — the US international layout doesn't support the character ẞ ).
Thank you for your analysis, it makes total sense.
Now, when talking about the regular alphas, I can absolutely see why @HoodrowThrillson prefers to take some artistic liberty (or rather: keep the inherited liberties), because putting the secondary uppercase letters in the top-right really would look wrong - don't you agree?
To each his or her own, of course, BUT... I totally disagree: getting the secondary uppercase legend in the lower right corner is precisely what looks dead wrong to me. And since the US international layout adds so many letters to the tertiary (AltGr) and quaternary (AltGr-Shift) layers, it looks VERY wrong.
I have to respectfully disagree. Putting alpha legends in the bottom right corner is a stylistic choice that is acceptable to make. Alphas occupy both the shifted and non-shifted positions (in this case both AltGr and Shift+AltGr). This is something that's been done in professionally designed keyboards for decades, for obvious reasons (it looks better). As a matter of fact, you'd be hard-pressed to find any keyboard that does it the way you described with both legends in the top, i.e. the 100% proper way.
Alphas do differ in casing between shifted and non-shifted positions, but any user that is familiar with keyboards and the Latin alphabet will be able to (intuitively) deduce that the uppercase character is produced by holding Shift, even if the legend is located near the bottom. So there is no issue going with the aesthetically more pleasing choice in this case.
For example, this is why it was okay for Apple to put uppercase alphas in the bottom left corner on their Extended Keyboards, while keeping numbers and symbols in their usual positions. They didn't totally flip the base and shifted layers around; they just chose to put alpha legends in the bottom left corner for aesthetic reasons, and it didn't impact usability negatively because humans don't take things that literally.
However, what is not okay is putting symbols in places where they can't be produced, or which correspond to other characters. If a symbol is produced by holding Shift+AltGr and pressing 1, the only acceptable position for the sublegend (from a usability standpoint) is the top-right corner of the 1 key. Similarly, if a symbol is produced by holding AltGr and pressing 2 (and Shift+AltGr+2 does nothing), the only acceptable position is the bottom right corner of the 2 key. Doing it differently is bad because, unlike putting alphas in the bottom corner, it literally misrepresents the layout and impacts usability.
Here's an IBM Russian/English keyboard to demonstrate what I mean:
Alphas can be seen in both the top and bottom corners, but the symbols are always in the correct positions.
In summary, these are the parts I agree with and believe should be changed in the set:
Note aside: the C with cedilla is pictured as lowercase: ç instead of Ç.
HOWEVER, several symbols are accessed through AltGr, but they are placed in the upper right corner instead of the lower right corner: ² ³ € ¥ « » ... they should be moved down.
If it isn't done now, who knows if it'll ever be done.
The rest of the legends, especially the alphas, are fine.Edit: You'll notice that there are several options for the pipe key. This is because it isn't as clear-cut as the rest. The sublegends here are actually being used to represent two distinct things: alternative layout options with the
⌫ (similar to
Lock/
Control), and US-International characters with the
¬ and
¦. It's up to the runner to decide whether he wants to go with a mixed approach (1°, 2°) or stick to just one (3°, 4°). That being said, any of the four options in the above image is correct, it's just the original Griseann one (bottom
⌫, top
¬) that's wrong.
