Each layer style has its own collection of properties in the Timeline panel.

Align With Layer

Uses the bounding box of the layer to calculate the gradient fill.

Altitude

For the Bevel And Emboss layer style, the elevation of the light source above the layer, in degrees.

Choke

Shrinks the boundaries of the matte of an Inner Shadow or Inner Glow prior to blurring.

Distance

The offset distance for a Shadow or Satin layer style

Highlight Mode, Shadow Mode

Specifies the blending mode of a bevel or emboss highlight or shadow.

Jitter

Varies the application of a gradient’s color and opacity.

Layer Knocks Out Drop Shadow

Controls the drop shadow’s visibility in a semitransparent layer.

Reverse

Flips the orientation of a gradient.

Scale

Resizes the gradient.

Spread

Expands the boundaries of the matte prior to blurring.

Use Global Light

Set this to On to use the Global Light Angle and Global Light Altitude in the Blending Options property group instead of the individual layer style’s Angle and Altitude settings. This is useful if you have multiple layer styles applied to the same layer and want to animate the position of the light for all of them.
