Up to 3 modes can be used per Keystone 2 function. They change the way Keystone 2 groups keyframes when processing them. These modes are accessible using hotkeys as follows:
Layer mode (default) click
Property modeALT (⌥) + click
Global modeSHIFT + click
Layer mode
By default, with a simple click, keyframes are grouped by layers.
Layer mode example
Property mode
ALT (⌥) + click allows to group keyframes by property. Particularly useful when you want to stagger or align keyframes located on a single layer.
Property mode example
Global mode
SHIFT + click groups keyframes all together. This is the combination to use if you have selected keyframes on multiple layers and want to maintain their relative offset.
