Exporting or Backing Up Key Bindings in LOL
If you need to export, import, or backup your key bindings or key configurations you can do so easily because all your key settings are stored in a text file called input.ini.
The location is in:
C:\Riot Games\League of Legends\Config\input.ini
Note that this is a text file so you can open it up in Notepad and edit it or at least review it.
 Uses for this file
- Move your settings from one PC to another
- Backup your ini setting if you need to reinstall Windows
- Give your settings to a friend
