(from Yitzhak)

This band adds handling for the "5" key in the numeric keypad.  This is
called VK_CLEAR in the VK_ constants.  Using this band, and with
NumLock off, doing 5 will send NetHack the letter 'g'.  Doing SHIFT-5 will
send 'G'.  Without this band and with NumLock off, 5 does nothing.  With
NumLock on, 5 sends 5.
