 101 been deleted, the QEMU Block layer returns -EIO which results in IO
 102 errors in the guest for applications that are reading/writing to the device.

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