Exit shortcut keys don't work when nnn is launched in the tmux command

[kaysond]

I'm trying to use a fish shell function to start nnn automatically in tmux so the preview comes up without any extra commands.

My command is currently
NNN_PLUG="p:preview-tui;c:autojump" tmux set -g status off\; new-session -- nnn -c -a -Q -d -i -P p $argv

This works, and most features work fine. I get very strange exit behaviors though:

• ctrl+q does not work at all
• q works sometimes
• ctrl+g works
• if I try to exit while the preview script is still running, the preview script keeps running and makes tmux stay open until I ctrl+c

If I run tmux manually, then nnn inside, I don't have any of these issues.

Any ideas what I'm doing wrong?

Turns out it's because when you run tmux with a command specified, it uses default tty settings, which have xon/xoff. If you run it with your shell first, it inherits those tty options which in my case, apparently, it turns those off.

The example https://github.com/jarun/nnn/blob/master/misc/quitcd/quitcd.fish file shows the stty commands to fix this
