Explanation of the Quick Select dialog box.
Apply to
Applies the filter to the entire graph or to the current selection set (if it exists). To select the set of objects in which the filter will be applied, use the Select Objects button. When you have finished selecting objects, press ENTER to redisplay the dialog. "Apply to" will be set to "Current Selection".
If "Append to current selection set" is selected, the filter will be applied to the entire drawing.
Selecting objects
Temporarily closes the Quick Select dialog box, allowing the user to select the object to which the filter will be applied. Press ENTER to return to the Quick Select dialog box. Change the Apply To box to display the Current Selection. The Select Objects button is only available if Include in New Selection Set is selected and the Append to Current Selection Set option is cleared.
Object Type
Specify the type of objects to be included in the filter criteria. If the filter criteria is being applied to the entire drawing, the Object Types list contains all object types, including custom ones. Otherwise, the list contains only the object types of the selected objects.
Besides using a LISP routine, I use the FILTER tool and have a selection set saved. Just make sure the only filter is "Block" and you can drag+select the entire drawing to grab only blocks. Usually I have to do this a few times due to nested blocks.
