It would be nice to see the selection zone for your cursor, or maybe cross hairs. See image:
Not being able to select what I want causes me to zoom in, make my selection, zoom out, find where i want to copy from, then paste. I'm currently working on a job where there is not a wall in the building that is square with the world. So i have to use reference points to get the angle i need to move or copy and item.
Using tab doesn't work ether when you want a specific item. Tab starts selecting multiple items... when all i want is one item.
See attached video of a great example of the frustration of trying to select something in Revit.
