 By default in OpenBSD & FreeBSD (and probably on macOS as well), `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-selection 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.
 
-##### Restrict file open
-
-In order to disable opening files on accidental navigation key (<kbd>→</kbd> or <kbd>l</kbd>) press:
-
-    export NNN_RESTRICT_NAV_OPEN=1
-
-Use <kbd>Enter</kbd> to open these files.
-
-##### Restrict 0-byte files
-
-Restrict opening 0-byte files due to [unexpected behaviour](https://github.com/jarun/nnn/issues/187); use _edit_ or _open with_ to open the file.

-    export NNN_RESTRICT_0B=1

 ##### 100% CPU usage
 
-There is a known issue where if you close the terminal directly with `nnn` waiting for a spawned process to exit, a deadlock occurs and `nnn` uses 100% CPU. Please see issue [#225](https://github.com/jarun/nnn/issues/225) for more details. Make sure you quit the spawned process before closing the terminal. It's not a problem if there is no spawned process.

Please see issue [#225](https://github.com/jarun/nnn/issues/225) for more details. Make sure you quit the spawned process before closing the terminal. It's not a problem if there is no spawned process (`nnn` isn't blocked) as `nnn` checks if the parent process has exited.
