Using the Parameter UI
In addition to typing values directly, many parameters provide interactive UI controls that allow values to be adjusted quickly.
These controls typically include modifier arrows and sliders, which can be used for incremental adjustments or continuous value changes.
Modifier keys can also be used to change the behavior of these controls for finer or larger adjustments.
Modifier Arrows
Many parameters provide modifier arrows next to the value field.
These arrows allow users to increment or decrement the parameter value.
The amount of change applied with each click depends on the parameter's unit step, which defines the base increment used when modifying the value.
For many parameters, this default step value is 1, meaning each click increases or decreases the value by one unit.
Modifier Keys
Modifier keys can be used while clicking the modifier arrows to adjust the step size.
ALT + Click
Increase step size by 10×
ALT + Shift + Click
Increase step size by 100×
Shift + Click
Reduce step size to 1/10
Ctrl + Shift + Click
Reduce step size to 1/100
These modifiers allow both fine adjustments and large changes without modifying the parameter step settings.
Sliders
Some parameters provide sliders that allow values to be adjusted by dragging the control.
Sliders are useful for quickly adjusting values and visualizing the parameter range.
Snapping with Shift
Holding Shift while dragging a slider enables fixed step snapping.
This causes the slider to move in consistent increments, often rounding to clean values.
For example, if a slider is currently set to 4.3%, holding Shift and moving the slider will cause it to snap to 10%, 20%, 30%, and so on.
This makes it easier to set precise rounded values.
Extending Slider Range
In some cases, the slider range may be smaller than the full parameter range.
Holding ALT while dragging allows users to move the slider beyond its visible range, accessing the full parameter limits.
This makes it possible to quickly exceed the slider's default range without changing the parameter configuration.
