How it works
Every letter has a tall twin, called a capital. Tapping a key on its own gives the small letter.
A sentence starts with a capital, a name starts with a capital, and the word I is always a capital.
To make a capital, hold the shift key with one hand and tap the letter with the other.
Each side of the keyboard has a shift key. Hold the one on the other side from your letter, then let go of both.
