Hi Paul,

Your PC is fine - you just need to change what you entered in as the command part of the shortcut there.

Just put the text:      ToroidalHelix

in for the command part of the shortcut key to make that key trigger that plug-in command.

Also the files for the command (ToroidalHelix.js and ToroidalHelix.htm) need to be copied into the \commands sub-folder inside of MoI's main installation folder.
