Value Slider
To the right of each slider is a second control, called a value slider. This control displays
the parameter’s current numerical value and has arrow buttons on either side.
Some parameters have sliders with effectively infinite ranges, such as scale, which can
be set at any value positive or negative (although the indicator can only display 6 or 7
digits).
Left arrow
Right arrow
Value sliders lack the relative positioning feedback that traditional sliders provide, but
they can be dragged directly to modify the value.
To modify the value of a parameter using a value slider
Do one of the following:
µ
Click the left or right arrows to decrease or increase the value one increment at a time.
µ
Option-click the arrows to decrease or increase the value by .01.
µ
Double-click the number and type a new value directly in the field.
µ
Click directly on the numbers and drag either left and right or up and down to decrease
or increase the value.
Note: When you position the pointer above a value slider, the pointer changes to a
four-way arrow. If you begin by dragging up or down, subsequent horizontal movement
will be ignored. If you begin by dragging left or right, subsequent vertical movement will
be ignored.
Coordinate Controls
Parameters that define a specific location in the Canvas are controlled using three value
sliders to set the x, y, and z axes; parameters that define a specific location in a
two-dimensional object have two value sliders for x and y.
