Modal Usage

When you run Set Origin Rotation From Face

1. Preview - The transform is applied immediately so you can see the result.
2. Selection - Press Left Mouse to select faces for the origin rotation to be taken from.
3. Flip axes - Press X, Y, or Z to flip that axis (negate). Each key toggles on/off.
4. Confirm - Press Enter or Space to keep the changes.
5. Cancel - Press Escape or Right Click to revert to the original state.

A GPU overlay in the bottom-left of the 3D viewport shows the current flip state and hotkey hints.
