Automatic Backup Feature
Starting from the 3.2 version Hot Keyboard has automatic backup feature. When Hot Keyboard is started (manually or automatically with Windows) it backups its current state and all macros into the following folder:
Hot Keyboard keeps 20 previous files
Hot Keyboard does not do backup if there already is a backup that was made today and you don't do significant changes to your macros (i.e. if you add a lot of new macros Hot Keyboard will make new backup anyway).
If for some reason you need to restore from an automatically created backup, go to File -> Import... and select the backup file.
