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 that 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 been 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.
