 102 submitted against the host device underlying the disk.  Once a drive has
 103 been deleted, the QEMU Block layer returns -EIO which results in IO
 104 errors in the guest for applications that are reading/writing to the device.

 465 key or @code{#} followed by the raw value in either decimal or hexadecimal
 466 format. Use @code{-} to press several keys simultaneously. Example:
 467 @example

 471 This command is useful to send keys that your graphical user interface
 472 intercepts at low level, such as @code{ctrl-alt-f1} in X Window.
