相撲外：Ctr shortcut when RET not available

Other GNU Emacs tips

I've encountered a freak error in GNU Emacs on the Nokian N900: when entering some passwords, the RET (Enter) key stops working, i.e. all the text can be entered, but pressing RET doesn't send it.

If you encounter the same problem, use:

C-j

This will send RET.
