emacs 4: Offical Tutorial Part 3

>> Type C-x 1 to get rid of the buffer list.

When you have several buffers, only one of them is "current" at any
time.  That buffer is the one you edit.  If you want to edit another
buffer, you need to "switch" to it.  If you want to switch to a buffer
that corresponds to a file, you can do it by visiting the file again
with C-x C-f.  But there is an easier way: use the C-x b command.
In that command, you have to type the buffer's name.

>> Create a file named "foo" by typing C-x C-f foo <Return>.
   Then type C-x b TUTORIAL <Return> to come back to this tutorial.
