I'm running Ubuntu 16.10 with Cinnamon, and I'd really like to be able to type diacritics. I saw this post:
How can I type accentuated characters like ë?
But I can't seem to set a "compose" key. I go into Settings->Keyboard->Layout->Options.
I expand "Position of Compose Key", and choose "Right Alt".
But...nothing happens. If I go into LibreOffice and type:
RightAlt: nothing happens Shift-Quote: I get a double-quote e: I get a lowercase letter "e"
But what I want is the "e" with the umlaut (?) above it.
