You can look up cd and mkdir in the man pages (`man <some name>`). To look for
something where you are not sure, use `apropos <something>`.
vi is a very powerful text editor, there are whole books written on it. ZZ (not
zz) is the same as :wq or :x as they save the file and exit.
for !! and !s, try `man history`
The others are for shells (usually bash) (also look at `man line`), usually in
scripts. Again, there are whole books on writing shell scripts. The man page
for bash is reasonably complete, but cryptic for new users and very long.
