I've never seen this side column in an Excel worksheet before. What is it called?

Clicking on the '2','3', and '-' buttons seem to show/hide rows 3-4; clicking the '1' button seems to do nothing.

It is data grouping / outlining.

Check the Data tab/menu, specifically the "Outline" commands, group, ungroup, and subtotal.

Search help for "group" or "outline"

This is the "outlining" feature of Excel. It allows you to group rows together so they can be expanded/collapsed easily. It is useful if you're making a sheet that has heirarchical data in it. I'm not sure about Excel 2010, but in earlier versions, you can access the feature via Data -> Group and Outline.
