You can filter the list of buffer objects by usage, or, for OpenGL ES only, by the last bound target column. The bottom part of the view shows the size of the currently selected buffer objects. If no buffer object is selected, the size of all the displayed buffer objects is shown.

To filter the view to show only the buffer objects with a given usage or last bound target, use the Filter box. For example, type transform into the box and the view only shows you the buffer objects that have transform in the usage field. See 5.21 Filtering and searching in Graphics Analyzer for more information.
