#  Note on the principles...
#
#  Each opened file is a "buffer" (b-commands, as above) 
#  with the content in its edited state, able to be saved
#  back to that file or elsewhere.
#  The buffer is displayed in a "window" (Ctrl-w commands, 
#  as below); any window can show any buffer, and there can 
#  be multiple windows.
