A method of rendering text on an output device using a pre-developed image of a custom font. The composition contains, as an essential ingredient, a cationic compound of general formulaY+R1R2R3R4X\u2212whereinY may denote nitrogen or phosphorus,R1, R2, R3 and R4 independently of one another may denote an unbranched or branched C1-C20-alkyl andor a C6-C20-aryl group as well as a C6-C26-aralkyl group, andX\u2212 may denote an anion of an inorganic or organic, mono- or polybasic acid. The second elastic member is spaced from the first elastic member and the power transmission control mechanism in the direction of the axis of rotation. This reduces inconsistent placement of the finger and provides consistent release alignment.
