About Text 8-5

■ Use one of the keyboard protos to create keyboard views in your applications.

These protos include the

protoKeyboard, which creates a keyboard view that

ﬂoats above all other views. The keyboard protos are also described in

“Keyboard Views.”

The Keyboard Registry 8

You need to register any custom keyboards or keypads that you create with the

Newton system’s keyboard registry. Caret insertion writing mode is used whenever

the user enters text from a keyboard or keypad. When a registered keyboard or keypad

is opened, the system knows to display the insertion caret at the proper location.

The Newton system also allows you to customize the behavior of the insertion

caret and key presses by calling your application-deﬁned methods whenever an

action occurs in a registered keyboard or keypad.

For more information about the keyboard registry, see “Using the Keyboard

Registry” (page 8-36).

The Punctuation Pop-up Menu 8

The user can tap the insertion caret to display a Punctuation pop-up menu. This

menu, shown in Figure 8-1, provides an easy way to add punctuation when writing

with the stylus.

Figure 8-1 The Punctuation pop-up menu

Choosing any item on the Punctuation pop-up menu inserts the appropriate

character into the text, at the insertion caret. The bent arrow, at the top left, is a

carriage return, and the blank box at the bottom indicates a space.

You can override this menu with your own caret pop-up menu, as described in

“The Caret Pop-up Menu” (page 8-38).
