M-b and M-f do not work as expected.

Now the C-h works as Backspace but the other two keys don't (M-b and
M-f). Can someone tell me what is the mistake in the following jedrc?:

IGNORE_BEEP = 0;
define keybindings_hook (emulation)
{

        unsetkey ("^H");
        setkey ("backward_delete_char_untabify", "^H");
        unsetkey ("\eb");
        setkey ("bdelete_word", "\eb");
        unsetkey ("\ef");
        setkey ("delete_word", "\ef");
        setkey ("toggle_line_number_mode", "\eL");
}


Currently these two keys bring up the Buffers and File menu
respectively. They aren't getting unset.
