A lot of the Blackberry Secret codes are actually shortcuts to the hidden menu areas that people are simply not aware of.

You will need to be on the Home screen when you enter these codes..

Key shortcuts:
A or C = phonebook
S = search
F = phone profiles
W or B = browser
H = help
K = locks the keys
L = calendar
V = messages
M = messages folder
R = alarm
T = tasks
U = calculator
I = applications
O = options
P = phone
Some new additions thanks to the contributions in this thread:
T - Top of page (in browser)
B - Bottom of page (in browser)
Space - Page down (in browser)
ALT + Right Shift + Del = hard reset
D - Memo pad
U - Switch between hide/unhide in title bar (in browser)
