and will end with a. After the last quote, type in your message. Then click on "submit" and the message will be sent.
If the message is too large to fit on the screen, you can scroll down by clicking in the down arrow right under the x and to the extreme right of the screen.
If you have to scroll sidewise, there is the same kind of arrow on the lower left of the screen. Click on that to slide the message so you can read the whole line.
I hope this helps.
