I only recently discovered that you can click on the Alt key tooltip text to pick up an item or loot a corpse in addition to the item itself. This made life so much easier with things like books hidden under skeletons and piled up corpses. I am not sure if that's new, or if it somehow took me until patch 9 to realise! Does that help with your ... ogre problem? There might still be things without tooltips that this doesn't address.
