You can quickly add a keyframe in Motion using a specific keyboard shortcut after modifying a parameter.
According to the provided information, you can add a keyframe to the last parameter you modified by pressing Control-K.
Here's how this method works based on the reference:
- Modify a Parameter: First, make an adjustment to a parameter of a layer or object in your project. This could be changing its position, scaling it, rotating it, adjusting opacity, etc. You can do this using onscreen controls or directly in the Inspector.
- Press Control-K: Immediately after modifying the parameter, press the keyboard shortcut Control-K.
Result:
Pressing Control-K adds a keyframe to that specific parameter you just altered at the current playhead position on the timeline.
For example, if you use the onscreen handles to increase the size of a layer and then press Control-K, a keyframe will be added to the Scale parameter of that layer. This shortcut is a fast way to set animation points for parameters you are actively adjusting.
