The AutoSave desk accessory from Magic Software automatically saves data from
any Macintosh application to the currently logged disk by periodically invoking
the Save command from the File menu. The user can set the frequency of saves
from 1 minute to 1 hour, as well as stop the automatic save at any time.
NowSave, a module of the Now Utilities package, also works with any application
and saves at preset, user defined intervals (either based on time or the number
of keystrokes or mouse clicks).
