Running Boot Camp in Windows 7 with Bluetooth Wireless Keyboard and Wireless Magic Mouse

Question

NOTE: I was installing a fresh copy of Windows 7 Professional on a 27" iMac mid-2010 with a Processor Speed of 2.93 GHz, a Core i7 Processor Type,  a Quad Core Processor Configuration, 8GB RAM, and a ATI Radeon HD 5750 Graphics Card.  I run Snow Leopard so it is a 64-bit OS.  I have a Wireless Keyboard and Wireless Magic Mouse as well.  In order to install Windows 7 you need a Wired Keyboard and Mouse.  You will also need a Wired Keyboard and Wired Mouse to update Boot Camp.
Updating Boot Camp Assistant (VERY IMPORTANT)
First, plug in a wired keyboard and wired mouse.  The Boot Camp Assistant version that came with my iMac was 3.0 so I upgraded it to 3.1 and then to 3.2.  I'm not sure if only the upgrade to 3.1 is necessary, but I took it a step further.  I was told by Apple Tech Support that you first needed to upgrade to version 3.1 before being able to upgrade to 3.2  These upgrades will not be found using Software Update on the Mac.  However, they can be found at http://support.apple.com/downloads/#macoscomponents
They also have software updates for 32-bit machines as well and MacBook Pro updates.
NOTE: Before updating the version of Boot Camp, but after installing Windows 7 and after putting in the Mac OS X Install DVD to run Setup.exe to download the Mac drivers, run Software Update for the Mac while logged into Windows 7 by clicking on Start - All Programs - Software Update for any additional updates.
Next I installed Boot Camp Software Update 3.1 for Windows 64 bit found at http://support.apple.com/kb/DL1336
I then ran Software Update for the Mac while logged into Windows 7 by clicking on Start - All Programs - Software Update
Then I installed Boot Camp Software Update 3.2 for Windows 64 bit found at http://support.apple.com/kb/DL979
I then installed Boot Camp 3.2 Update for iMac (early 2011) found at http://support.apple.com/kb/DL979 but I'm not sure if this was necessary.
Once Boot Camp 3.2 has been installed I ran Software Update for the Mac again while logged into WIndows 7 to make sure I had all the updates.
Configuring a Bluetooth device on a Windows-based computer
(from http://support.microsoft.com/kb/952818)
How to make sure that the Bluetooth service is started (MY COMPUTER WAS ALREADY SET UP TO RUN BLUETOOTH, SO THE NEXT 8 STEPS COULD BE OPTIONAL)
Open the Microsoft Management Console (MMC) snap-in for Services. To do this, follow these steps.
Windows Vista or Windows 7Windows XP
Click Start, and then click Run.
Copy and then paste (or type) the following command in the Open box, and then press ENTER:services.msc
Click Start , copy and then paste (or type) the following command in the Start Searchbox, and then press ENTER:services.msc
In the Programs list, click Services.
If you are prompted for an administrator password or for confirmation, type the password, or click Continue.
Double-click the Bluetooth Support service.
If the Bluetooth Support service is stopped, click Start.
On the Startup type list, click Automatic.
Click the Log On tab.
Click Local System account.
Click OK.
If you prompted to restart the computer, click Yes.
How to connect the Bluetooth device to the computer
1. First off, you need to go into Mac OS and remove the keyboard and mouse from your Bluetooth settings entirely. You'll add them back in later (see 9) below).
2. Boot into Windows using a USB connected Mouse and Keyboard.
3. Go to Control Panel – Hardware and Sound – Device and Printers – Add a Device
4. Turn on the Mouse to send out a signal and once it sees it select it to be paired to the computer
5. Run 3.) again except select the keyboard.
6. Turn on the Keyboard to send out a signal and once it sees it select it to be paired to the computer by typing in the 8 digit number into the wireless keyboard and hit ENTER/RETURN.
7. To see if everything was added go to Devices and Printers and see if they were added to the list.
8. Shutdown Windows 7 and Restart using Mac OSX.  If you adjusted the Boot Camp settings while in Windows 7 you will see a Boot Camp icon in the system tray located at the bottom right of the screen.  From here you can logoff and reboot in Mac OSX.  If you don't, do a RESTART and hold the Option key down after hearing the GONG and select the Mac HD option while logging in.  Now it's time to add back the wireless mouse and keyboard to be recognized by your Mac.
9. Go to System Preferences – Internet and Wireless – Bluetooth
10. Hit the “+” button to launch the Bluetooth Setup Assistant to find the devices sending out the signal.
11. Highlight the device found and hit “Continue”
12. Do this for both the keyboard and mouse.  You will be prompted to type in the 8 digit code into the wireless keyboard in order to pair it with your computer.
13. Click on the pinwheel next to the “-“ sign to rename the wireless devices if you'd like.
I then logged back into Windows 7 to see if the mouse and keyboard were functional and had no problems.  For some reason, Windows has problems pairing bluetooth devices that are already paired under a Mac OSX.  Many people have updated Boot Camp, yet still were not able to pair their wireless devices because they didn't break the Bluetooth connection on the Mac side first. So both steps are necessary (1) Updating to at least Boot Camp 3.1 if not 3.2 and (2) Deleting the Wireless mouse and keyboard link while running Mac OSX before trying to pair them in a Windows OS.

Answer 1

I found the answers by trial and errors.
@  is obtained by CTRL + OPT + 2
#   is obtained by CTRL + OPT + 3
(without shift or caps lock)
These two signs are critical and I fail to understand why this information is not readily available from the help function or from the Apple support.
