ControlMap.addAxisToTriggerMapping c_GIMouseWheelUp -1 IDFMouse IDAxis_2 0
ControlMap.addAxisToTriggerMapping -1 c_GIMouseWheelDown IDFMouse IDAxis_2 0

This is probably OFN to those that have dug into the controls.con file with notepad and made adjustments to their keybinds directly. The mousewheel defaults to the next-weapon, previous-weapon menu on the right which is painfully slow and if you’re using it as your main weapon select system chances are you’re getting owned. Some people use the numbers across the top which is also subject to problems of striking the wrong key at the wrong time, forward strafe and try to select you knife.

My Documents\Battlefield 2\Profiles\0001 is where your primary controls.con file is located, open it up in notepad.

Down towards the bottom you'll find the default mouse wheel assignments:

ControlMap.addAxisToTriggerMapping c_PINextItem -1 IDFMouse IDAxis_2 0
ControlMap.addAxisToTriggerMapping -1 c_PIPrevItem IDFMouse IDAxis_2 0

The first one is mousewheel up, second one mousewheel down

Cut the first line and paste under the heading at the top of the file labeled:

ControlMap.create InfantryPlayerInputControlMap

paste it under the line:
ControlMap.addKeyToTriggerMapping c_PIWeaponSelect1 IDFKeyboard IDKey_1 10000 0
ControlMap.addAxisToTriggerMapping c_PINextItem -1 IDFMouse IDAxis_2 0

now change it to read like so:

ControlMap.addKeyToTriggerMapping c_PIWeaponSelect1 IDFKeyboard IDKey_1 10000 0
ControlMap.addAxisToTriggerMapping c_PIWeaponSelect1 -1 IDFMouse IDAxis_2 1

We've now assigned the mousewheel up action to select the knife directly, changing the 0 to a 1 at the end tells the game that this is your secondary key/button assignment. You can do the same thing for the mousewheel down action only assign it to the pistol.

ControlMap.addKeyToTriggerMapping c_PIWeaponSelect2 IDFKeyboard IDKey_2 10000 0
ControlMap.addAxisToTriggerMapping -1 c_PIWeaponSelect2 IDFMouse IDAxis_2 1

Happy knifing and pistol sniping, or assign whatever weapon you want to this fast switch method.

The file is separated into 7 sections.

1. Infantry
2. Land
3. Air
4. Helicopter
5. Sea
6. Game Control (GUI, and other ingame things)
7. Player Input (Mouse look, camera, change inventory)

---------------
Controller Type
---------------

This is tied into the second part (after the .)
It's pretty simple

IDFKeyboard - Keyboard Key
IDFMouse - Mouse
IDFGameController_0 - Joystick (If you have more than one, change the _0 to read _1, _2, etc. **It always needs a 
number and even if you have 1 stick, it should read _0. Remember computers start count at 0, not 1)

The reason why this is needed is because you can bind Axis controls to Keyboards, Mice, AND sticks. Same with 

Triggers.

-----------------
Key, Button, Axis
-----------------

This is where you select the key that is being bound.
I've included a list of what every key is called.
You should have no problem binding joystick buttons or mice buttons (I use a bunch on my Logitech MX510). I also 
didn't include what they are because every joystick and mouse are different.

-------------
Keyboard Keys
-------------

IDKey_KEYNAMEHERE

The Alphabet is just the letter (A-Z)
The Top number row are just the numbers (1-0)
The F keys just F1-F12

Special Keys
------------

` - Grave
Print Screen - PrintScreen
(Top row number line)
- - Subtract
= - Equals
Backspace - Backspace
Tab -Tab
CAPS - Capital
Shift - LeftShift/RightShift
Control - LeftCtrl/RightCtrl
Alternate - LeftAlt/RightAlt
Windows Key - LeftWin/RightWin (Yes I was suprised it used these as well!)
Space - Space
[ - LeftBracket
] - RightBracket
\ - Backslash
; - Semicolon
' - Apostrophe
, - comma
. - period
/ - slash
Return (or enter) - Enter
Insert - Insert
Delete - Delete
Home - Home
End - End
PageUp - PageUp
PageDown - PageDown
Number Pad Numbers - NumPad1-0
Number Pad / - Divide
Number Pad * - Multiply
Number Pad - - Minus
Number Pad + - Add
Number Pad Enter - NumpadEnter
Number Pad . - Decimal

I think that's all of em!

------------
Key Variable
------------

This is what defines the key to be either one shot or press and hold repeat or double tap. (Confusing??)

Okay example, when you press W to walk forward, you would set that to hold and repeat. If it was one shot, your guy 
would walk forward one step and stop. And example of one shot would be weapon select. IF you press 3 to select your 
main gun, it chooses it. Even if you hold down the key it will only go once then stop. If this was set to hold 
repeat, your gun would be continously switching between firing modes. Double tap are keys like sprint (I think that's actually the only one that is double tap).

The codes are as follows

0 - Hold and repeat
1000 - Double tap
10000 - One Shot

I experimented with changing some of these from their defaults to different types and the game doesn't like it very well. I suggest you keeping all of the defaults the way they are.

If you are building the Controls.con file from the ground up, I suggest looking at the default one for the proper 
settings. I'm not going to post all of them here.

--------------------
Primary or Alternate
--------------------

It's a good idea to follow all of the lines with a 0
This signifies the default button
If you want an alternate button do the following
Copy and paste the line you want an alternate to
Change the appropriate key
Change the final 0 to a 1.
-------------
**JOINT BINDS
-------------

Treat these binds the same as single binds but you need to enter 2 keys or buttons or axis. 
UP then DOWN
RIGHT then LEFT

It's a bit backwards (normally it's left then right).

THe way these are designed you cannot make one a mouse button and one a keyboard.

The only way to go around this is to make one set primary and the other alternate.

------------------

Well I think that just about wraps it up. If anyone has any questions after, please don't hesistate to ask.

I'm also TRYING (repeat) TRYING to learn Visual Basic to create a small program to make this bind file with ease.

I'll let you know if I come up with anything or if anyone else has more programming skill than me (I can set the clock 
on the VCR), let me know if you want to help out.

Good Luck!
