Action

SPACE : determine other button meaning (+ / -)
A : increase / decrease polygon angle
R : increase / decrease aperture radius
P : increase / decrease propagation distance
X/Y/Z : increase / decrease rotation angle around XYZ axis
L : enable / disable lens effect
C : convex / concave lens
F : increase / decrease focal length of lens
D : increase / decrease pitch width of propagation distance
