The filtering works everywhere, from battle scripting to rituals to research.

In case someone doesn't know already... You can copy and psate commanders' and units' orders. To paste, hover the mouse over the line of text that has the command and press Ctrl+number, and to paste hover mouse over the command and press a number. Commanders' orders can't be given to units and vice versa.

You can use 'y' key to give battle orders to all armies moving INTO the target province (instead of the armies that already are in the province).
