##### BSD terminal issue
By default in OpenBSD & FreeBSD, `stty` maps <kbd>^Y</kbd> to `DSUSP`. This means that typing <kbd>^Y</kbd> will suspend `nnn` as if you typed <kbd>^Z</kbd> (you can bring `nnn` back to the foreground by issuing `fg`) instead of entering multi-copy mode. You can check this with `stty -a`. If it includes the text `dsusp = ^Y`, issuing `stty dsusp undef` will disable this `DSUSP` and let `nnn` receive the <kbd>^Y</kbd> instead.
