607 ------- -----
|

608 sound A string of raw sound data, or the name of another sound to

609 play. The symbol `t' here means use the default X beep.

624 systems support sound.
|
|
0
|
625
|
|
|
626 - The pitch, duration, and volume options are available everywhere, but
|
|
|
627 many X servers ignore the `pitch' option.
|
|
|
628
|
|
|
629 The following beep-types are used by emacs itself:
|
|
|
630
|
|
|
631 auto-save-error when an auto-save does not succeed
|
|
|
632 command-error when the emacs command loop catches an error
|
|
|
633 undefined-key when you type a key that is undefined
|
|
|
634 undefined-click when you use an undefined mouse-click combination
|
|
|
635 no-completion during completing-read
|
|
|
636 y-or-n-p when you type something other than 'y' or 'n'
|
|
|
637 yes-or-no-p when you type something other than 'yes' or 'no'
|
|
|
638 default used when nothing else is appropriate.
|
|
|
639
|
|
|
640 Other lisp packages may use other beep types, but these are the ones that
|
|
|
641 the C kernel of Emacs uses.
