AOE3- Hot keys

What are some hot keys that help you alot from time to time? I usually use the below ones extensively

'T' for town centre

'Ctrl+B/S/A/R/D' for Barracks, Stable, Artillery, Arsenal, Dock

'.' and '?' for idle villagers and explorer/s

'Ctrl+1', Ctrl+2, ctrl+3 for Infantry, cavalry and artillery (Needs to be assigned though)
