- Vim can edit several files at once. Each edited file is called a "buffer" in Vim terminology.
- One can open a new file using the :e [filename] command.
- One can switch to a different buffer using :bn (buffer-next), :bp (buffer-previous) and other commands.
- :bd closes the file.
- :ball - switches to split-screen for all buffers.
- :buffers - displays the current list of buffers.
