I am guessing so since thats how they are in the AOE games but want to make sure because I have the Strategic commander and all my stargey games don't allow unit production bindings so it lowers its usefullness.
Telephius, the AOK-engine has a hotkey-feature that allows you to build units very fast.
Look at
