iPad Keyboard Is Split
The Apple iPad has many specific features that take advantage of the device’s larger display. One such feature is the new split keyboard, which allows users to divide the keyboard into two sections. This helps users to type easily with their thumbs by separating the device’s on-screen keyboard. The two-thumb method of typing is likely the easiest and quickest way to enter text. When users utilize this feature, the keyboard splits to the left and right of the iPad’s display. The split keyboard feature allows users to undock and achieve greater flexibility when typing. When the keyboard is split, the keys shrink, so they become easier to use. However, most users don’t know how to un-split the keyboard.
