The MagMe hotkey necessary for easy navigation of the options of the software can not be used on laptops with the US keyboard, as the "key below esc" is not the same as in UK keyboard, and that very key is not available in the UK keyboard layout. The best way to improve on this seems to be allowing users to modify the hotkey to their preference. At the moment, for example, users can't exit the software easily unless they use a keyboard with a UK layout.
This was a kinda known issuse, the plan was to allow the magic-hotkey (currently ~) be edittable by the end user as well as allow the user to edit the keys that are used with it in combo.
