How it works & useful details
How to use this tool
Drag either control point or focus it and use arrow keys. Shift moves ten steps. Play a single preview to compare the resulting motion.
Supported values and limitations
X coordinates are bounded from 0 to 1; Y coordinates from -1 to 2 allow overshoot. Exact numeric inputs and presets provide keyboard alternatives. Animation runs only when requested, lasts at most three seconds and respects reduced-motion preferences.
