@Yuca is right - there is no built-in hotkey. Instead, you will want to record a macro using this link to get you started.
When you record a macro, it translates the clicks and actions you perform into VBA code. The biggest challenge you will have here is getting VBA code that will be general enough to apply to any chart, but specific enough to format it properly. It can be done, but you may need to record 2 or 3 versions of the macro to get it right.
