10/09   How do I get emacs to reread the contents of a file
        and junk the contents of the buffer corresponding to
        that file? I know I can C-x C-f to re-read, but I'm
        looking for something like C-r in Lynx.
        \_ I can suggest M-x revert-buffer (you could bind it to some other
           key sequence, though C-r is not recommended).  --sowings
           \_ I won't use C-r, C-x r maybe. Thanks.
