Blackbox does not have a default macro installed for just that, but you can create a new macro and insert the following:

“<Alt-PRESS><Print Screen><Alt-RELEASE>RSEIUB”

This will create a working macro for writing any data in cache to disk, kill all processes (Sigkill), remount mounted disks and perform a reboot.
