9.3.3 Mechanically operated controls
Some provision is required to ensure mechanically operated controls can easily be located, identified and have their status determined via non-visual means without activating them; and which are both visually and tactilely distinct from non-active features. The controls need to be operable with limited force and dexterity and allow the key repeat rate to be adjusted.

9.3.3.1 Analysis
Addresses user needs: 3-1, 3-2, 3-3, 3-4, 3-5, 3-6, 4-3, 5-3, 6-1, 6-2, 6-7, 6-8, 6-10, 6-11, 6-12, 6-13, 6-15, 6-16, 6-17, 6-18, 8-1, 8-2, 8-3, 13-1.
Sufficient extant standards coverage exists to draft procurement legislation for significant portions of user needs, but additional investigation is required for newer kinds of mechanical controls.
