Shape

3 of 14 differ

Body shapeiDescribes shell symmetry, not the intended hand. Symmetrical with side buttons on one side differs from an asymmetric right-handed body. Ambidextrous means a symmetrical body with side buttons on both sides.

Symmetrical body1Maker product pagemicrosoft.com/en-us/d/surface-mouse-2nd-edition/8wg5vqp0x4bvRead 21 October 2026Page: contoured, ambidextrous design. The four buttons are all on the top, with no side buttons, so the schema value is symmetrical.
