391

392 channel -- The event channel, a frame or a console. For
|
|

393 button-press, button-release, misc-user and motion events,
|
|

394 this must be a frame. For key-press events, it must be
|
|
|
395 a console. If channel is unspecified, it will be set to
|
|
|
396 the selected frame or selected console, as appropriate.
|
|
|
397 key -- The event key, a symbol or character. Allowed only for
|
|
|
398 keypress events.
|
|
|
399 button -- The event button, integer 1, 2 or 3. Allowed for
|
|
|
400 button-press, button-release and misc-user events.
|
|
|
401 modifiers -- The event modifiers, a list of modifier symbols. Allowed
|
|
|
402 for key-press, button-press, button-release, motion and
|
|
|
403 misc-user events.
|
|
|
404 function -- Function. Allowed for misc-user events only.
|
|
|
405 object -- An object, function's parameter. Allowed for misc-user
|
|
|
406 events only.
|
|
|
407 x -- The event X coordinate, an integer. This is relative
|
|
|
408 to the left of CHANNEL's root window. Allowed for
|
|
|
409 motion, button-press, button-release and misc-user events.
|
|
|
410 y -- The event Y coordinate, an integer. This is relative
|
|
|
411 to the top of CHANNEL's root window. Allowed for
|
|
|
412 motion, button-press, button-release and misc-user events.
|
|
|
413 timestamp -- The event timestamp, a non-negative integer. Allowed for
|
|
|
414 all types of events. If unspecified, it will be set to 0
|
|
|
415 by default.
|
|

416

419 `empty'.

1149 not the distinct character ``Control-I''.

1162 If USE-CONSOLE-META-FLAG is nil, this will always be the case. If
