Macro / Command QuestionFollow

Does anyone know if there is a way to Macro a command to make your hot keys change from one number set to another. For example rather than using the mouse or typing [shift]1 or [shift]2 to change the hot key sets, I would like a macro that would allow me to press 2 and switch to my #2 hotkey bar. I have not been able to find any information on this and any help would be appreciated. I there is no command that can be used in a macro but there is a way to do this using a custom command I can program that also. I have not been able to find any information on controlling the hotkey sets that way either.
Thanks for your help
