Select all TC’s, select all barracks, select all ranges, select all stables, select all siege workshops, select all castles and select all docks are absolutely crucial hotkeys to know and have for efficient gameplay. Alternatively if you’re simpleton like I am, you can use control groups and control group your buildings, but remember this makes microing multiple army groups or army composition harder as you can’t control group them.
Useful building goto hotkeys such as lumbercamp, mill, mining camp, blacksmith and university should be mapped out so you can use them when needed, this makes getting techs much easier.
