Happy ever since, writing English, Japanese, French and German with no problem (apart from the frequent typos, though). Have seen the driver on Windows and Linux, not sure about Macs
When I left Switzerland, I was a bit lost only having "kezboards" without the "ä" etc. My solution is now a US-keyboard combined with the "US-International" keyboard-driver.
I never used email before coming to CH, so as far as I know, @ has always AltGr-2. Until I wanted to use my bro-in-laws laptop on holiday in Barbados that is, and had to ask his son where the @ was, as I couldn't see it .
Don't blame the IT guys for everything, it was the bloody printers that caused all the chaos by not agreeing on anything .
For umlauts on a Mac with a US keyboard, press Option+u, then type the character you want with an umlaut.
For example Option+u, then = ü
Similarly, for accute accents use Option+e, and for grave accents use Option+[the ~ key].
shift plus three letters what here around has to be availalbe as one single letter ? No, such machines cannot be sold in Switzerland, neither in France or in Turkey (Türkiye)
