Dogleg keybuttons, such as keybutton 10, present unique problems with respect to guiding the keybutton for up/down movement inasmuch as the area upon which an operator may strike the button is large and is not positioned directly over the axis of the stem of the keybutton 12. When the keybutton is struck in a region displaced from stem 12, there is an inherent tendency to cause the stem 12 to bind within the chimney 14. One technique for stabilizing the keybutton 10 is to reduce the amount of sideplay or potential rotation about an axis perpendicular to the stem 12. This may be accomplished with a stabilizer bar which is then mounted with pivots on the keyboard plate 16. These type devices are well known in the art and are utilized, but are expensive.
