Use the following shortcuts to get the most out of your calendar...
Double-click any blank space in the calendar to begin creating a new event.
Or drag the plus button from the lower right to any cell in order to start a new event.
Double-clicking on the clear space on any day also brings up an option to jump to that day on the Day tab.
Click on the little triangle at the upper right of the sidebar to hide it and make more room for the calendar itself.
You can also hold down option/control while dragging an event to duplicate it.
Oh horizon view, shift-clicking on the arrows on either side of "today" will move the calendar one day in either direction instead of one-page in either direction.
