After asking around elsewhere, I've learned that binds are saved, not reloaded from config like, say, TF2. This fixes one of my problems, but I've realized that it's impossible to create a bind that will create a name with a space in it. Observe:
AutoHotkey seems useful if I'm looking to rebind my mousewheel for something, but what about the example I gave in the original post? I can't see a way to modify options.xml to set up the proper bind.
Another thing of note is that I can't find anything that takes advantage of the numpad numbers... I'd guess it's just "NumpadX" but confirmation would be nice.
