Auto-Saving: Protection Against Disasters
Emacs saves all the visited files from time to time (based on
counting your keystrokes) without being asked. This is called
"auto-saving". It prevents you from losing more than a limited amount
of work if the system crashes.
When Emacs determines it is time for auto-saving, each buffer is
considered and is auto-saved if auto-saving is turned on for it and it
has changed since the last time it was auto-saved. If any auto-saving
is done, the message `Auto-saving...' is displayed in the echo area
until auto-saving is finished. Errors occurring during auto-saving are
caught so that they do not interfere with the execution of commands you
have been typing.
