I'm always running tmux so it's not typically a feature I look for, but as you mention it doesn't seem to trigger a find for terminal scrollback. Wezterm doesn't do this either so maybe that's an iTerm thing. I always assume Ctrl keybindings will trigger emacs mode shortcuts in the tty.
Update: Windows Terminal doesn't do it either.
I would love to use tmux. I have used yazi in the past and I really liked it but I was barely using it to its fullest potential.
I think I have "skill issue" regarding tmux and I used to use hyprland (recently went to niri) and I just always preferred opening up another terminal I used to use (which was foot back when I was using my own config and it was alacritty on cachy/ idk what was on omarchy for the time I was on omarchy but I don't like omarchy)
Is there actually a way to fix this skill issue, like I want something so simple in start that I just run it and forget and still get decent amount of benefits?
