Before you accept and participate in free advice from someone on the Internet, please be aware that changes to system settings such as .ini files can cause your game to lose stability or worse. Make sure you understand the risks involved, and have a backup available.
- Open Windows Explorer and navigate to the folder SteamApps\common\Conan Exiles\ConanSandbox\Saved\Config\WindowsNoEditor
- Locate the file input.ini
- Right-click and drag file to a blank area, when you let go of the right mouse button, select Copy here. This will create a backup of the file called “input - Copy.ini”
- Double-click, or right-click | Open with … input.ini so that it loads in a text editor like Notepad
- Hit Ctrl + F and search for TogglePlayersList. It should look like this if you want to map it to B:
ActionMappings=(ActionName=“TogglePlayersList”,Key=B,bShift=False,bCtrl=False,bAlt=False,bCmd=False)
