CTRL+Left doesn't skip a word to the left

[jerkstorecaller]

I'm on Windows, using MobaXterm to SSH to Ubuntu and running crush over SSH. My $TERM is tmux-256colors.

Every single Linux TUI app I've ever used lets me use Ctrl+Left to skip one word to the left, except crush. Yes, I know Alt+Left works, but Ctrl+Left is engraved in a muscle memory and is more important to me than using crush.

How can I fix this? The crush-config skill doesn't know anything about this.

I don't want to reconfigure my terminal, or change terminal apps. I just want crush to behave like a normal app. Is that doable or nah?

$ cat -v
<here I press Ctrl+Left>
