Although sliders are fixed-range controls, some parameters can be set to values outside of that
limited range. For those parameters, a second type of slider control is available—a value slider,
which is described in the next section.
Change the value of a basic slider
Do one of the following:
m Drag the slider to the left to decrease values or to the right to increase values.
m Option-click to the left or right of the slider to decrease or increase by a value of 1.
Value slider
Although basic sliders are fixed-range controls, some parameters can be set to values outside of
a limited range. For those parameters, a second type of slider control is often available, known as
a value slider. A value slider appears as a light gray number, often to the right of a basic slider. For
example, the Amount parameter in the Gaussian Blur filter has a basic slider with a default range
of 0 to 64; however, you can adjust this parameter up to 600 using the adjacent value slider.
Parameters with effectively infinite ranges, such as Scale, can be set to any positive or negative
value. The value slider can display up to 18 digits to accommodate large values.
Modify the value of a parameter using a value slider
Do one of the following:
m Drag right or left over the numbers to increase or decrease the value.
To change the value in larger increments, press Shift while dragging. To change the values in
smaller increments, press Option while dragging.
m Click or double-click the number, then enter a value in the field.
Coordinate controls
Parameters that define a specific location in the Canvas are controlled using three value sliders
to set the X, Y, and Z coordinates. Parameters that define a specific location in a two-dimensional
object have two value sliders, for X and Y coordinates.
Note: In most cases, only the X and Y axis value sliders are visible; clicking the adjacent disclosure
triangle displays both value sliders in a vertical stack. However, for 3D groups operating
with three dimensions, clicking the adjacent disclosure triangle reveals the additional Z axis
value slider.
