DirectX Scancodes

When modding Fallout New Vegas, you will come across mods that add new features like weapon inspects and ammo checks.
To use the features you will need to press a button.
In most cases if you want to change/customize what button you want to use, you can pause the game and go into the MCM (mod configuration menu) find the mod and change the buttons.
But this is not always the case.
The mod maker needs to make this a feature and they don't always do it.
In most cases however, they do add an ini. file that allows the user to customize settings on their own.
But of-course it's not as easy as just saying ''use key X to activate the mod feature''.
No, Fallout New Vegas uses DirectX to represent keyboard keys.
And you will need to change these numbers to your desired key.

In the next section I will list all the codes you use and their corresponding keyboard key.
The important parts to look at are:
Dec - for the number
Button - for the button you want it to become

But for now I will first show you an example of how to use these codes and change a mod key use.
For an example we are gonna use ''Tactical Freelook - ESPless''
https://www.nexusmods.com/newvegas/mods/93490

First make sure the mods works that you are gonna use, make sure all the requirements are met and that you can use the mod in game.
Now outside of the game we need to find where the mod is installed and find the customization ini. file.
To find it in your game files, I recommend:
Right click on the game in your Steam library.
Browse local files.
Then go into the Data folder.

Now to make it easier on you, go to the download link of your mod, click on files and click ''Preview file contents''.
This will show you the file structure and what path you will need to take to get to the ini. file.
Just follow the folders till you find the ini. file and open it, if it ask with what program use notepad.

In this case we need to go to:
📁 Config > 📁 Stentorious > 📄 Freelook.ini (1.3 kB)

Now we need to find where it uses the code for the key.
Here it's iKeyBind = 56.
Change the 56 to the number/letter you want (See below section).

Make sure to save and now you can head back in game to test out if it worked.
