E too many keys

ERROR: Too many keys to fit a 104 key keyboard.

You will need to redefine your keybindings so that you can use things effectively. Here is a list of keys you should deconflict. If messing with the keybindings corrupts your config file, it may cause crashes. If you get crashes, make sure your options.txt file is fixed. You can always delete it and try again. You can set a lot of keys to Esc for None so that you won't activate them. This can cause non-standard buttons to activate them though sometimes (calculator, music/volume buttons, etc).
