A fastener driving tool includes a control assembly that allows the tool to be fired sequentially by first placing the tool against a workpiece followed by actuation of a trigger to fire the tool. The control assembly includes a valve assembly that allows the tool to be selectively adjusted to operate in a multi-shot sequence or a single shot sequence. In the single shot sequence the tool may only be actuated once upon placement of the tool against a workpiece and subsequent actuation of the trigger. The tool must be removed and repositioned on the workpiece before the tool can again be fired. In the multi-shot sequence, the tool may be repeatedly fired by repeated actuation of the trigger once the tool has been placed on the workpiece.
