A materials handling vehicle including an operator's compartment with a control module including control structure including a fin- shaped handhold element upstanding from an upper surface of the control module. The fin-shaped handhold element may include control structure for controlling at least one vehicle function. The fin-shaped handhold element may be shaped such that an upper portion distal from the upper surface of the control module overhangs a lower portion more proximal to the upper surface of the control module so as to form an undercut area between the upper surface of the control module and the upper portion of the fin-shaped handhold element. Further, an adjustable palm rest may be provided to allow an operator to position their hand at a desired position relative to the control module.
