I just assumed that doc is outdated, since even the menu items described in
there did not match the current image. It is 2 years old so lots of things
have changed.

I actually ran into the exact same MNU  error about StrikeFont. But the
actual switching of the system font worked, and I verified it is using the
vector engine by slightly rotating a window, which otherwise would cause
ugly artifacts.

So I think this doc describes how to try the Vector engine before it was
actually integrated into Morphic.
Someone who knows the current state of affairs needs to fix the
documentation. I should have filed a GitHub issue but that was literally my
first hour with Cuis 😅

I’ve done it now:
