Write with your finger
Handwriting mode lets you enter text by writing characters on the screen with your finger. In
addition to normal text entry, use handwriting mode to enter your iPhone passcode silently
or open apps from the Home screen.
Enter handwriting mode. Use the rotor to select Handwriting. If Handwriting isn’t in the
rotor, go to Settings > General > Accessibility > VoiceOver > Rotor, then add it.
Choose a character type. Swipe up or down with three fingers to choose lowercase,
numbers, uppercase, or punctuation.
Hear the currently selected character type. Tap with three fingers.
Enter a character. Trace the character on the screen with your finger.
Enter an alternate character. To use an alternate character (a character with an accent or
umlaut, for example), write the character, then swipe up or down with two fingers until you
hear the type of character you want.
Enter a space. Swipe right with two fingers.
Go to a new line. Swipe right with three fingers.
Delete the character before the insertion point. Swipe left with two fingers.
Select an item on the Home screen. Start writing the name of the item. If there are
multiple matches, continue to spell the name until it’s unique, or swipe up or down with two
fingers to choose from the current matches.
Enter your passcode silently. Set the rotor to Handwriting on the passcode screen, then
write the characters of your passcode.
Use a table index to skip through a long list. Select the table index to the right of the
table (for example, next to your Contacts list or in the VoiceOver Item Chooser), then write
the letter.
Set the rotor to a web browsing element type. Write the first letter of a page element
type. For example, write “l” to have up or down swipes skip to links, or “h” to skip to
headings.
