I was not aware of this, but found a similar solution that is available almost on any computer: On Linux (my main work environment) I use the English International with AltGr Dead Keys. This gives me a lot of European (and other) accents by combining AltGr+<Accent simulation key> <Letter on which to put the accent>.

Examples:

ä - AltGr+" a (the double quote looks visiually like 2 dots)

ç - AltGr+, c

õ - AltGr+~, o

and so on. I found this solution very practical, even if quite late in my life (went from German QWERTZ, to French AZERTY, to end up with QWERTY), because QWERTY is available everywhere, even if I have to work remote through Windows computers, and it is much much friendlier than AZERTY/QWERTZ. Additionally it gives me to write with the same layout German, French, Portuguese, etc. And it is very easy to remember how to get the accents, because the used signs are visually close.
