 Yes, but <UP><DOWN> and tab file/command completion don't. 
 
No, none of those exist in the original 'sh' (Bourne Shell), not even
in fairly recent varieties, such as in late-90s IRIX.  However, command
line editing (using a large subset of vi commands) and command history
exist in the Korn Shell (ksh).  You might have been confused by that,
since many recent UNIXes provide an "sh" as a symlink to "ksh", just
as
linux provides "sh" as just a symlink to "bash".
