This is a fast communication grid for people who can use a keyboard.
Type your messages and press F1 to speak. F2 deletes a word and F3 clears the text. As you type, the autocomplete prediction finishes your words for you (you can press F4 if it is the wrong suggestion). You can select a message from your saved messages using the up and down arrows. When you type a word, it searches the message list for your word. Press F5 to speak the selected message. When you have written a sentence that you want to save to your phrase list, press F6. To edit an existing message, select it and press F7. Press F8 to remove a message from the list.
