Switching buffers on write...

Hey Guys,

I suspect this question has been asked and answered before but I haven't found any relevant answers.

I would like to map the command:

:w new_filename

to do the following two things

:w new_filename
:e new_filename

I thought I would implement this with an autocmd on the BufFilePost event. My challenge is how to access the new_file_name value. I checked the help docs on registers but didn't see anything relevant there....
