Two lid catches that must be both slid simultaneously to open product
Holding a ctrl key down with another key - or a mouse button
Any chordic input.
You can have these - you just have to have another way of doing the same
thing that doesn't require simultaneous.

Gregg,
For the sake of clarity, can you please give an example of what you would
expect to be covered under "simultaneous actions".
Thanks,
Rob

Suggest we add "simultaneous actions" to old provision S 1194.23 (k)(2)
Simultaneous is mentioned in performance criterion, but not here. One hand
does not preclude simultaneous. Suggest simultaneous be added here with the
rest so that it reads
(2) Controls and keys shall be operable with one hand and shall not
require pinching, twisting of the wrist, tight grasping OR SIMULTANEOUS
ACTIONS. The force required to activate controls and keys shall be 5 lbs.
(22.2 N) maximum.
