How do you open a file from within Vim?

Question

I know how to open a file in Vim from a terminal (vim fileName). What I can\'t figure out is how to open a file when I\'m already within Vim.

I tried :

Answer 1

Also, to open multiple files (or just one, so I tend to use this for opening a single file, since :e fails to open multiple files)

:n file1 file2

:n resets the argument list so it is as if you had entered them on the command line (so commands like :rew will work with this list), but :e does not.
