`nnn ` is now packaged for Solus.

On at least FreeBSD & OpenBSD, typing `^Y` will send a `DSUSP` signal, suspending the process. Annotate the issue along with a solution to allow `^Y` to work on these.

There may be similar issues on NetBSD or possibly on OSX, but I don't have either available for testing.

Turns out ^B is also intercepted by Windows.

^V does not work while working on Windows. It is intercepted as paste.

Removed file manager and desktop search keys.
Both can be launched with launcher key.
