Transform
Resetting rotation, matrix and origin

The right-click menu with the Transform submenu open

The Transform menu

Right-click menu › Transform. The commands work on the matrix of each selected object, each around the center of its own bounding box: the object stays in place.

ItemWhat it does
Reset rotationremoves the rotation, turning around the center. Scale and skew remain
Reset transformthe matrix becomes a plain translation again: rotation, scale and skew are removed, and the center stays where it was
Bake transformrotation, scale and skew go into the geometry, and the matrix remains a translation to the center. A shape becomes a path (a rotated rectangle does not exist), a path changes its geometry in place, a group passes its matrix on to its children. It does not apply to text, images and use. The stroke width carries the scale along, unless it is Non scaling
Reset originthe origin goes to the center of the bounding box and the geometry compensates: visually nothing changes

Each one is an undo step. The items are disabled when there is nothing to work on.
