1) Under normal circunstances for flight the Condition Levers would be 'AUTO' position. Retarding it from the 'AUTO' position, the Condition Lever will come to the 'FTR' (feather) position.
2) As you correctly mention there is a Botton that has to be used to pass it then from the 'FTR' position to the 'FUEL SO' ('Fuel Shut Off', and therefore Engine Shutdown). This is to prevent inadvertently shuting down the engine.

The Condition Lever of the ATR has 4 positions. '100 OVRD', 'AUTO' (characterised by a notch), 'FTR', and 'FUEL SO'.
In the older models (300) there is no '100 OVRD', or 'AUTO' positions, but the operation principle is the same.
