Newbie scout question

Use the "n" key to select units who have not made a movement that turn. This is helpful for any and all stealth unit/armies that you happen to forget.

Just keep hitting the "n" key during your turn. This will automatically take you to every unit with "defend", "hide", or "siege" orders.

This way you can give each unit an order, and you know are you finished when it starts cycling back through the units that you actual want to "defend", "hide", or "siege".
