Have a 'Total' Option
If you select part of a column in Excel, it will provide a total as well as the number of rows selected.
It would be great to have this feature in Access.

It's already available and has been for some years (Access 2013?). On the Home tab is a Totals icon. Click that and you will see the ability to add totals at the bottom of the table/query/datasheet. Click in the field where you want a total and select the type of total (sum, average, count, etc.) you want.
