reverse function

i have searched on the forum and in my manual, but still i cannot find a reverse function. i thought this would be a simple operation, but i just cannot find the option.
can anyone help??
peace

First, have you update to the new OS 2.1? If you haven't, the reverse function isn't there... you'll also need the new maual.

If you have - goto the trim mode -> edit, and it in there.

ok, my mate says he can upload the new operating system for me, but where can i get the new manual?
