accent characters - RESOLOVED

RESOLVED - compose key was mapped to a key that was being used for something else

Mageia 8
Plasma
LibreOffice 7.0.4.2
Liberation Serif

In older versions this worked by pressing stuff like <Ctrl+accent>, letter but not now?

How does one add accented characters to a text document today?
Thanks
