BlackBerry Wireless Handheld
 Getting started
Before you begin
Before you use your handheld, you should familiarize yourself with 
some of its basic components.
Your handheld’s keyboard provides access to the alphabetic 
characters. The keyboard also features nine special keys: the Delete 
key, the Backspace key, the Enter key, the Space key, two Shift 
keys, the Alt key, the Escape button, and a Power button. You can 
use the Power button to activate backlighting and you can generate 
numbers, symbols, punctuation marks, and special characters by 
pressing the Alt key in combination with the alphabetic keys. The 
trackwheel helps you navigate, view, and select items on each 
screen. To scroll through menu items or text, roll the trackwheel. To 
select applications and menu options, click (press) the trackwheel.
