Keyframe assistants

Bulk operations on keyframes and layer timing. All of them are in the top-bar Animate menu; the easing ones are also in the Animation menu bar entry.

Easy Ease

Easy Ease All in the Animate menu applies it to every keyframe on the selection at once — the fastest way to de-mechanise an animation you built with linear keys.

Time-Reverse Keyframes

Reverses the selected keyframes in time. The values stay; the order flips.

The obvious use is turning an entrance into an exit. Apply the entrance preset, duplicate the keyframes later in the timeline, and reverse the copy.

Sequence Layers

Lays the selected layers’ bars end to end, so each starts where the previous one finishes. Useful for shot-style sequences and for anything that should play one-at-a-time rather than together.

Stagger Animations

Offsets each selected layer’s start by a fixed amount — 0.3 s by default.

This is the workhorse for card grids, lists and menus: apply one preset to every card, select them all, stagger. Keeping the ease identical and varying only the timing is what makes a group read as one movement.

Smooth Motion Path

Ctrl/⌘ + Alt + S.

Smooths the spatial path of the selected layers’ animated position, removing the corners you get from keyframes that were placed by hand.

Keyframe interpolation

Animation → Keyframe Interpolation → Linear and → Hold set the interpolation type on the selection directly, bypassing the ease presets.

Hold is worth remembering: it makes a property jump rather than travel, which is how you do stepped motion, hard property cuts, and frame-by-frame swaps.

The ease clipboard is not an assistant, but it belongs here

The Graph panel’s ease clipboard — Copy and Paste — moves a cubic-Bézier ease from one keyframe to any number of others, across properties and layers. In practice it does more for consistency than any of the assistants above. See Easing.
