To begin with, just try going to Tools>Macro>Record New Macro. Now give your macro a name and click OK
Now just do whatever it is that you want the macro to do and when you're finished, go to Tools>Macro>Stop Recording.
Now you have recorded the macro and what you want it to do. Every time you want to use it you go to Tools>Macro>Macros and select it OR you can assign it to a button by drawing one and right clicking then choosing Assign Macro
