Keymaster moves, copies and reshapes keyframes so you can adjust a whole animation without editing each property separately. It is a free micro tool in Motion Dock.
The four large tiles handle timing. Move an animation to the playhead, copy it, play its keys backward, or change its duration.
The small controls nudge keys by frames, stamp a new key, and open More for value math, thinning, expression baking and separate Position dimensions.
Keep an animation together
Select keys across several properties or layers. Keymaster treats their timing as one group, keeping the offsets between them when you move or copy. If no keys are selected, it uses keys in the work area on selected properties. The selection rules explain the scope of each action.
For a first result, move three keys to the playhead. Each action is one After Effects undo step.
Preview the idea before clicking
Hover over a timing tile to see its diamonds show the operation. These are small diagrams inside Keymaster. Hovering does not change the composition.
In a roomy slot, a hint beneath the controls describes the action and its modifier. Compact slots keep the controls and show tooltips when you hover.
