Within the Key-Tap Feedback section you see in Figure 6, the Sound checkbox is checked by default. This means that you hear a clicking sound from the Tab 4 every time you tap a key on the keyboard.
The size of the keyboard doesn’t change even if you enlarge the font size on the screen. If you need to see a bigger version of the key character you’re typing, tap Character Preview. Every time you tap a key on the keyboard that has a character in it, such as a number, letter, or punctuation mark, you’ll see a blue bubble pop up right above the key so you can see the character of the key you’re pressing.
