You can select more than one table row at any given time. Rows can be individually selected or a block of rows can be selected at once by first left-clicking the selection box of the first row in the desired block and then shift-clicking the selection box of the last row in the desired block. The Select All or Deselect All buttons can be used to select or deselect all objects in the table. The table summary at the bottom of the table includes the total number of items that are selected.
