Yeah you use f2 or something (I forget :\, but it's super useful).
Comsat, turrets, science vessels, overlords, spore colonies, observers, cannons.
Mutalisks/scourges vs another zerg is basically what you will be using anyways, so obviously they beat each other. Vs terran, scourges to take care of science vessles, that's all terran will be using most of the time. Scourges vs protoss corsairs since that's all they'll be using, but usually zerg should be the one using air units.
