The sec mouse button means the right mouse button if you are using a right handed mouse setup.

To switch between scopes with a dual scope setup, hit left ctrl+right mouse button.

The "sec" button is the Secretary of Defense button. It is the button you press whenever your economy is going bad, or your lodge buddies can't get enough of the peoples' wealth.

You only tap the right mouse button. If you hold it too long it does something else.
