Did you know if you disable your home screen dialing, you will be able to access a whole slew of shortcuts on your Blackberry (aka Crackberry)?  It’s true!  Here is how to do it.  I found this information on a great website which I have linked to down below. 

From the article:

Disable home-screen dialing:
1. Click phone icon
2. Hit the left-side convenience key
3. Go to Options > General Options > Dial From Home Screen > No

Now, with a single keystroke, you can access all of the following apps:

F = Profiles
L = Calendar
A = Address Book
M = Messages
V = Saved messages
C = Compose

K = Lock Keypad
B = Browser
R = Alarm
S = Search
T = Tasks
U = Calculator
O = Options

Let’s say you like that dialing from the home screen feature. You can always wait for your Blackberry to auto-lock, but compulsive checkers will appreciate the ability to glance and lock multiple times a minute.

Option 1: Assign lock to a convenience key
Options > Screen/Keyboard > Left (or Right) Side Convenience Key Opens > Lock.

Option 2: Alt + Enter
If when you hit this combo, you get a language input option, then disable this first by going to Options > Language > Use Input Language Shortcut > No. Now it should work.
