| 477 currently executing. SOUND specifies the sound to make and DEVICE the | |
| 478 device to make it on (defaults to the selected device). | |
| 479 | |
| 480 SOUND is either a string (raw data to be played directly), a symbol, or | |
| 481 `nil' (equivalent to the symbol `default'). Sound symbols are looked up in | |
| 482 `sound-alist', and resolve either to strings of data or to other symbols. | |
| 483 Sound symbols that map directly to data should be considered named sounds; | |
| 484 sound symbols that map to other sounds should be considered abstract | |
| 485 sounds, and are used when a particular behavior or state occurs. | |
| 486 | |
| 2757 | 487 Remember that the sound symbol is the *second* argument to `ding', not the |
| 793 | 488 first. |
| 489 | |
| 490 The following abstract sounds are used by XEmacs itself: | |
| 491 | |
| 492 alarm when a package wants to remind the user | |
| 493 auto-save-error when an auto-save does not succeed | |
| 494 buffer-bound when you attempt to move off the end of a buffer | |
| 495 command-error any uncaught error (i.e. any error that the user | |
| 496 sees) except those handled by undefined-click, | |
| 497 undefined-key, buffer-bound, or read-only | |
| 498 default used when nothing else is appropriate. | |
| 499 isearch-failed unable to locate search text during incremental search | |
| 500 isearch-quit when you delete chars past the beginning of the search | |
| 501 text in isearch | |
| 502 no-completion during completing-read | |
| 503 quit when C-g is typed | |
| 504 read-only when you try to modify a read-only buffer | |
| 505 ready when a compile or other time-consuming task is done | |
| 506 undefined-click when you use an undefined mouse-click combination | |
| 507 undefined-key when you type a key that is undefined | |
| 508 warp XEmacs has changed the selected-window or frame | |
| 509 asynchronously -- e.g. a debugger breakpoint is hit | |
| 510 in an asynchronous process filter | |
| 511 y-or-n-p when you type something other than 'y' or 'n' | |
| 512 yes-or-no-p when you type something other than 'yes' or 'no' | |
| 513 | |
