11,buffer: C-x C-b: if you find a new file with C-x C-f in the
Edwin,the first file remains in the Edwin,Type C-x C-b
to find them (it shows a list of all the buffers now in
the Edwin). Any text you see in the Edwin, has to be
in some buffer. if you have edited a file or something
and go to another file without saving the first one, the
changes would not save, unless you reback to the first
file, and C-x C-s. There is a way to save all the changed
file, that is C-x s. the command goes through the list
of buffers, and saves every changed buffer.
