I'm sure that this info can be found either on BBForums or in the manual but I figured it might be helpful to some to either keep a list of these keys for each BB type. I figured I'd setup the 8820 list.
Note: These keys can only be used by turning off "Dial from Home Screen" under Phone->Options->General Options. To use them, simply get to your home screen and TAP the button (don't hold it down or it will dial speed dial).
Q -> Enterprise messenger (not Blackberry messenger, it's the one that works with Sametime, etc)
W -> Web browser (for me it's the AT&T WAP Browser)
R -> Alarm Settings (handy when you need to turn it off real quick)
T -> Task List (self explanatory)
U -> Calculator
O -> Options menu (I find I use this one quite a bit)
A -> Address book
S -> Search your BB
D -> Memo pad (I believe it's D for documents)
F -> Profiles (Not sure if it's F for Fone Profiles or what.
)
H -> Blackberry Help (we can all use it sometimes)
K -> Keyboard lock (I prefer the mute method myself)
L -> Calendar
C -> Compose new SMS text message
V -> Go to your saved messages
B -> Blackberry Browser Bookmarks (Definitly deserves to be the letter B)
N -> Blackberry Messenger contact list
M -> Messages (Default view)
Hope that helped you along. Maybe someone else can do the same for the 8830, the Pearl, etc. Or BB can always send me a few of these and I can run through them for them .
Cheers!
