Control Control type Description
Slider Perhaps the most basic type of control,
dragging the thumb of a slider changes the
value of the parameter. Typically, dragging to
the right increases the value and dragging to
the left decreases the value. An example of a
parameter that uses a slider is Scale.
You can Option-click to the left or right of the
slider marker to decrease or increase by a value
of 1.
Value slider A special type of slider that includes the
numerical value of the parameter in the
control. Dragging the middle area (where the
number is) works just like an ordinary slider;
dragging to the right increases the value and
dragging to the left decreases the value. Some
parameters allow you to increase or decrease
the value indefinitely. Additionally, you can
click the increment or decrement arrow to
change the value one step at a time. You can
double-click the number itself to convert the
slider into a value field so you can type a
specific number directly into the control. An
example of a parameter that uses a value slider
is Position.
Note: When a value slider or value field is
active (highlighted), press Tab to move to the
next field.
Dial This control is used for values based on angles
or degrees. Rotate the dial by dragging it in a
clockwise or counter-clockwise motion. A
parameter that uses a dial is Rotation.
Value field This control allows direct entry of text to set
the value of the parameter. An example of a
parameter that uses a value field is the Text
Entry field.
Pop-up menu A menu with preset values. Click the menu and
choose the value you want. An example of a
pop-up menu is Throw Increment.
Value list Another type of pop-up menu. You can click
the arrow to the right of the field to display
preset values or you can type a value directly
into the value field. An example of a value list is
Typeface.
Activation
checkbox An on/off toggle for a parameter. An example
of an Activation checkbox is Preserve Opacity.
