Here is the source code for keyboard shortcuts with DLC (which only adds shortcuts to Espionage Overview and Religion Overview (in G&K) as you've found). I've modified it for readability. Taken from `\Sid Meier's Civilization V\assets\DLC\Expansion2\Gameplay\XML\Units\CIV5Controls.xml` as onuryn mentioned.
