If you don't know how they work, you press ctrl + F# and it saves the screen to that location, and pressing the button again will bring you back to it.
I've been trying to set my hatches as f5-f8, thus freeing 3 hotkeys (keep lair/hive on one just to upgrade). This is a lot faster and more streamlined than other larvae techniques, I feel, such as doing it by minimap or backspace, since this is direct and specific. I still keep all all hatches on one hotkey for unit production.
I hope everyone doesn't 1a, so this seems to be good for me. You'd have, say, lings/banes on 1, mutas on 2, banes on 3, infestors on 4, overseer on 5, nydus network on 0, and still have leftover for others.
Yay or ney?
