Every game.. no matter what.. try to do the following.
Hot key one SP 0
Hot key granary 7
Hot key market 9
Hot key GC 8
This helps you get upgrades quicker without searching for the building. Late in the game if you need to reassign these numbers to units go ahead.
I hot key my first horse scout 5.
My explorers get hot keys.
Something which I think may help me is hot key all my docks 6 and then TAB thru them to produce FB'w when booming or warships quicker by using the TAB. I am embarrassed to say I have not tried this, but will practice. Also when attacking with scythe hordes it is clear to hot key your stables and TAB, IMO. It sucks to hit ctrl LR ten times quickly and find out do to 1.5 speed/poor typing and lag you end up w/5 scythes/3 idle stables and two camels(ctrl LL !)
I think hot keying major production buildings and then TABing will help me produce more units faster. Aslo when I am spread all over the map, and I hit ctrl L.. I don't want to get my stable in my safe base... etc ... neilkaz ...
