How to choose selectable layers in ArcMap 10?

Question

Maybe I'm missing something, but I cannot figure out how to toggle selectable layers in ArcMap 10. In 9.3, I remember being able to choose from a list which layers I wanted to be able to select features from in the map. Let's say I'm editing two different feature classes for a building - 'FireExtinguishers' and 'EvacuationRoutes'. While editing, I don't want to accidentally select the 'Rooms' feature class. I want to be able to turn off the selectability of 'Rooms', but the only way I know how to change this is to right-click a layer in the Table of Contents and choose Selection -> Make This The Only Selectable Layer. I would like to have finer control over what layers are and are not selectable. Does anyone know how to do this?

Answer 1

In the Table of Contents window, there is a button across top titled "List By Selection". Clicking this button toggles the Table of Contents into a mode that lets you change the selectablity of each layer in your dataframe.
