 460 @findex sendkey
 461
 462 Send @var{keys} to the emulator. @var{keys} could be the name of the
 463 key or @code{#} followed by the raw value in either decimal or hexadecimal
 464 format. Use @code{-} to press several keys simultaneously. Example:
 465 @example
 466 sendkey ctrl-alt-f1
 467 @end example
 468
 469 This command is useful to send keys that your graphical user interface
 470 intercepts at low level, such as @code{ctrl-alt-f1} in X Window.
