10-key lesson 4: The 0 key with your thumb

The wide 0 key at the bottom belongs to your thumb. Numbers with zeros, like 100, 2050 and 30000, are some of the most common in real data entry.

Let your thumb rest lightly just above 0, so you can press it without moving your hand.

How each lesson works

Every lesson has three short exercises: the new keys on their own, a mix with keys you already know, and realistic numbers. Type each entry and press Enter. A wrong key turns red, and you can only move on with the right one. Pass with at least 92% accuracy. In the last exercise you earn up to three stars, depending on your speed in keystrokes per hour (KPH).
