Are there any keyboard shortcuts for the Windows version of the game? Other games that I have played will let you cycle through your buildings to collect from them, for example.
Unfortunately there are none that I am aware of.
The only shortcuts are the ones you can use in battle for summoning troops and using spells.
Are those documented somewhere?
You can see them when you are in battle, as the keys are displayed in the top left corner of each troop/spell.
