How to save as a new file and keep working on the original one in Vim?

Whenever I use the :sav command, it saves the file with a new name and opens the new file open in Vim.

Use the :w command with a filename:

:w other_filename

Assumed that I'm editing hello.txt.

• :w world.txt will write hello.txt's content to the file world.txt while keeping hello.txt as the opened buffer in vim.
• :sav world.txt will first write hello.txt's content to the file world.txt, then close buffer hello.txt, finally open world.txt as the current buffer.

After save new file press
