I'm using ZorinOS 15.3 Core on dual-boot system, with a US keyboard. I type mostly in English, but need to use accented characters from times to times when typing in French.
My current keyboard is set to 'US English', as i can't find 'International English'.
From what I have gathered so far on other forums, one path to resolution would be to declare a key such as AltGr (i.e. Alt-R) as a composition key, however, all how-tos I was able to find referred to settings as per Ubuntu, with no joy searching for 'Compose' or 'Special Character' in Zorin's Settings search bar.
Your help is kindly appreciated,
