I am pressing Ctrl+B, releasing both keys, and then pressing arrow keys, but it is not navigating (instead it is going through past commands as if Ctrl+B was not pressed). I'm using tmux in a SSH session on Mac. I've tried VSCode integrated terminal and Mac's terminal, both have the same issue. I have no ~/.tmux.conf file. Additionally, Ctrl+B, then release, then d successfully detaches. ctrl+b+n and other stuff works as well. It's just the arrow keys that won't navigate.
