Applying attributes to things...

First of all, it’s kind of weird that you can change the settings of wheels and hoverballs and then right click them to apply those settings, but you can’t do this with all of the tools. And second of all, if the settings include numpad key bindings, changing them won’t work at all, even though everything else can be set. So the only choice you have if you want to change the keys on something is to delete it and redo.
