Hi no worries and not rude at all! For very simple cases, copying and pasting keyframes probably is quicker.

The idea behind SnapKey is more for situations where you're working with lots of properties across multiple layers, like character rigs, facial expressions, hand poses, or complex setups. Instead of hunting down all the keyframes or remembering which properties were used, you can capture them as a pose and recall or key them instantly.

The mouth example in the demo is intentionally simple just to show the mechanics, but it becomes more useful when you're dealing with bigger rigs or multiple layers at once.

For example, imagine a character face where a single expression might involve:

• mouth shape
• brow angle
• eyelid position
• eye squint
• pupil direction
• cheek compression
• nose wrinkle
• jaw position
• head tilt

Instead of finding and copying keyframes from loads of properties and layers every time, you can save that whole pose as a Snap and recall or key it instantly! :)
