f. little (also in negative or restrictive meaning)

a. this occurs with so and adjectives when the main verb is be it is used for emphasis
b. such used with be means so much/so great

- If they were to escape, there would be no an outcry.
Were they to escape, there would be no an outcry.
- If you should hear anything, let me know.
Should you hear anything, let me know.
- If I had known, I would have protested strongly.
Had I known, I would have protested strongly
