hold the [SHIFT] button while selecting a crosspoint. The bus
containing that crosspoint is now locked into a shifted state. Any

The [SHIFT] button light will remain ON while the bus is in this
state.

Press and hold the [SHIFT] button. Select a crosspoint button. The
bus is now unshifted, and the [SHIFT] button lamp is OFF.

revert to the unshifted state. Simply pressing [SHIFT] will not have any
effect.
