Each geometric shape will show different editing options on non-drawing hand panel. It depends on the tool that you initially used for your sketch.

A. Simplify Points: Make a sketch object smoother by reducing control points.

B. Break Mirror: Bake mirrored part of the pair

C. Reset Thickness: Uniform stroke thickness

D. Break Symmetry: Separate an object created by polar symmetry into segments.

E. Snap: You can snap control points onto a point of another object.

F. Mirrored: Give exact mirror of individual models to World mirror plane. Mirrored object is synced to the original parametrically.

G. Loop: Connect start and end point of the geometry

Editing Properties Options 2

A. Simplify Points: Reduce number of edit points in geometry

B. Convert to SubD: Convert object to a SubDivision model. 

C. Loop V: Loop your surface in V direction

D. Loop: Connect end points of your surface in U direction.

E. Mirror: duplicate exact geometry on other side of axis

F. Snap: Edit points snap to each other

Editing Properties Options 3

Scale Arrow : You will see arrows if you are editing a primitive geometry. Pull the arrows to scale the object in both direction.

Primitive control point: (not show) Extra control points are available if you are editing a Superellipsoid. Move the points to find an interesting shape.
