    That's because the right Alt key isn't actually Alt, it's AltGr.
    PuTTY is British, and we don't have these keyboards with two Alt keys.
    This might be fixed at some point in the future:

    Both do the same thing for me on xemacs, but not on emacs. Since
    emacs understands the keys as RET and kp-enter, I think you need to
    fiddle with your emacs configuration to make the minibuffer understand
    kp-enter as well as RET.
