1. A key assembly comprising:

  • a rigid key configured to be depressed by a user;

    a leveling mechanism operatively associated with the key, the leveling mechanism being configured to constrain the key to a level orientation while the key is depressed by the user;

    a planar-translation-effecting mechanism operatively associated with the key, the planar-translation-effecting mechanism including one or more ramps that are configured to impart a planar translation to the key while the key travels downward on the one or more ramps as the key is depressed by the user.
