The present disclosure describes a taping tool for dispensing tape and mastic over gaps, seams, and/or joints between wallboard members that includes improved creaser wheel operation. The taping tool comprises an elongate body having first and second ends, and a creaser wheel pivotally mounted near the second end thereof for creasing dispensed tape. The creaser wheel is pivotable into a plurality of positions between a first position farthest away from the elongate body's first end and a second position nearest the elongate body's first end. The taping tool also includes an actuator for receiving user input indicative of a position of the creaser wheel desired by a user. In the absence of user input, the creaser wheel is configured to reside substantially in the first position. The creaser wheel is configured to pivot from the first position toward the second position in response to the receipt of user input.
