Thanks for the sharing the Swiss Keyboard layout. As already mentioned the Y and Z should be exchanged, Swiss keyboards are QWERTZ not QWERTY. I agree with the change in order of the lettering on the èü key, this is consistent with the other keys and same as on Lenovo and Dell layouts. I did notice that all other keyboard designs I have print the main alphabet keys as capitals and the èü éö àä keys in lower case. In the EVE V layout the special characters are capitalized. Given the oops!, ctrl, fn, alt and alt gr are all shown in lowercase I was wondering if this was a design decision or if it makes sense to print the "special characters" in lower case as well so they look less cluttered. Also if you compare to the Italian Keyboard layout the special character keys are shown in lower case.
Regarding the | and ¦ symbols the standard Windows Swiss German and French keyboards map AltGr+1 to ¦ and AltGr+7 to |.
On the Surface Pro 4 Keyboard there are additional symbols on the AltGr+4 (° degree symbol) and AltGr+5 (§ paragraph symbol) other keyboards I have don't have those symbols printed, so I guess it's a question of design whether to include those. I have no specific preference.
Thanks for the great work on bringing together the keyboard designs.
