Select multiple objects in navigator

I can see list of all objects (text boxes, shapes, images) in the Navigator (F5).
How can I use this list to select several objects? Holding CTRL and clicking on individual objects does not work.
My intention is to quickly select objects that I then want to delete.

Also, when I select an objects from the middle of that list and then press DEL to delete it, the selection in the navigator jumps back to the very beginning of the list instead of selecting the object before or after. In order to delete the next object I need to manually scroll through the whole list to select the next object.

Thank you in advance for all suggestions!
