Clicking on the decorator dot icon will add a Keyframe to that property. Clicking the rhombus icon again will remove the keyframe. A solid rhombus icon indicates there is a keyframe on the current frame, while a non-solid rhombus icon indicates that the property has a keyframe on another frame. Clicking the non-solid rhombus icon will create a keyframe on the current frame with the current property value.

Decorators make it quick and easy to glance over properties and see their state.
