Equivalent of vim's o or O commands

[Brian Adkins <lojicdotcom@gmail.com>]

I would like to have the equivalent of vim's o or O commands in emacs.
The o command will open a new line below the cursor and position the
cursor properly indented (if autoindent is on). The O command does the
same but opens the line above the cursor.

In emacs, C-o will open a line above the cursor if the cursor is at
the beginning of the line (but won't properly indent), but splits the
line if the cursor is within some text.

This is such a common operation for me, that I would like to bind it
to a simple combination instead of requiring C-e C-j.

I failed to find a good "emacs for vim users" reference on Google.
There are some partial ones that are helpful, but I would like a more
complete reference as I consider transitioning from vim to emacs. If
anyone knows of one, I'd appreciate a link.

Thanks,
Brian Adkins
