Sorry to hear that; did you export your accelerators previously as a backup?
No, it's a manual export from the Accelerators dialogue window. Perhaps a solution is to open a backup of your brain from a pre-7 install, export your accelerators to a *.csv and then reopen your latest brain with v7 and if the acceletors aren't there you can import the file.
Nice Zoner, hadn't spotted that!
