There is a shortcut: Press Q + click. Pressing Q turns on query mode for one click. I only included it that in the mouseover tooltips, fearing abuse. The server seems to handle it well, so query away.

The info overlays are also draggable, so one can make sense of their surroundings. See how this user mapped "his village": https://twitter.com/mc_sabourin/status/409592532452913152
