What If: ...Holding a certain key as you click the mouse doesn't select anything, but instead provides quick list-menu (to the side of the cursor) of the first 5 brushes or point-entities under the cursor. Hovering over an item in the menu highlights the item-in-question, and clicking selects. Letting go of the key makes the menu go away.
