Mirror Selection flips a selection to the opposite side of the mesh.

Axis

Choose on which axis the Mirror Selection will occur. The axis is based on the meshes origin. Therefore, if the origin is not centered within the mesh, the selection will have varying results.

Extend

The new selection will include the mirrored selection as well as the original.

Tip

With Extend activated, hold Shift while choosing an axis to include more than one axis in the selection. Otherwise, with Extend off, the mirror will take into account two to three axes.
