   Why do we say ``or it should be''?  When Emacs starts up using a
 window system, it determines automatically which key or keys should be
 equivalent to @key{DEL}.  So the @key{BACKSPACE} and/or @key{DELETE}
 keys normally do the right things.  But in some unusual cases Emacs
 gets the wrong information from the system.  If these keys don't do
