You can easily add macro shortcut icon on your toolbar in Corel Draw. Just click on Tools > Customization > Commands and select from list of macros the one you wish to add and drag icon to desired place. Just make sure that toolbars are unlocked.
But what if it’s not working?
If you are unable to add macro on your toolbar in Corel Draw - the solution might be very simple…. Maybe you are just using mouse as left handed - so you have switched primary buttons. My Corel Draw X5 is not available to drag and drop command icon to toolbar when using left hand mouse. When I switched buttons back - everything works again. So please try :)
