1. Introduction						*edit-intro*

Editing a file with Vim means:

1. reading the file into a buffer
2. changing the buffer with editor commands
3. writing the buffer into a file

As long as you don't write the buffer, the original file remains unchanged.
If you start editing a file (read a file into the buffer), the file name is
remembered as the "current file name".  This is also known as the name of the
current buffer.  It can be used with "%" on the command line |:_%|.

If there already was a current file name, then that one becomes the alternate
file name.  It can be used with "#" on the command line |:_#| and you can use
the |CTRL-^| command to toggle between the current and the alternate file.
However, the alternate file name is not changed when |:keepalt| is used.
An alternate file name is remembered for each window.
