Cool, it looks interesting :)

I haven't seen vterm flicker, though.  Perhaps it's because I'm
running emacs on wayland?

Yes, Alt is much easier.  It never worked before, though.

Hm, I've found that I can't use emacs on a remote machine when
connecting via ssh in vterm to a tmux session on that machine because
the local emacs intercepts the key presses and it uses them for itself
before they make it to the remote emacs.

I'm not sure what to do about that yet ...  Mabe eat is the way to go?
