Also...
...ruling out:
6. Caesar box
7. Scytale
8. Alberti disk
9. Jefferson's wheel cipher
10. Triangle code
Anything else requires (again) a keyword and extra aid, like:
1. Porta's cipher
2. Vigenère cipher
3. Carroll's cipher
I can also rule out these for the following reasons:
1. Masons' cipher (can't type on a keyboard)
2. Polybius checkerboard (no numbers)
3. Random substitution (no special characters)
4. Shadow's code (can't type on a keyboard)
5. Dancing men (can't type on a keyboard)
6. Poe's cipher (can't type on a keyboard and no numbers)
7. Playfair cipher (no numbers)
8. Typewriter code (no numbers)
9. Telephone code (can't type on a keyboard and no numbers)
