after two update's /neuron bind stop workink so i can't bind any key anymore. Is there any solution?

If you're on a french client, the shortcut has been translated (/neuron associer)
You could call /neuron to list what was localized or not :)

english localization

you can alt+click or shift+click (one of the two) the minimap icon to enter bind mode. You can enter any mode from the minimap icon.

I'll work on getting the slash command fixed

that work thx )

"/neuron bind" works perfectly for me. Is there a chance you were using a capital 'B' in Bind? Either way, I changed it so that it doesn't matter if you capitalize or not
