The Slider command creates a math entry input with an assignment var := val, with a visible slider.

The bounds option specifies the lower and upper bounds of the slider as a range.   If no bounds are given then the default slider range will be -10..10.  If val is outside the range of these bounds, if negative, the lower bound will be adjusted to match val, otherwise the upper bound will be adjusted to match val.

By default continuous=false, which means that the slider in the Learn interface will snap to the next integer value as it moves left or right.  Setting continuous=true will cause the slider to move to values that are a fractional division of the end points.
