I'm just starting to play the game and plan on speedrunning at somepoint. What keybinds do you guys recommend I use?

How so, I'm not sure if I have to do one run with supercell ID, and then another with Facebook, and so on and so forth. Is there a way to make multiple accounts fast and infinitely?

I'm interested in running Town Hall Any% as I've never ran CoC before and I want to know how to get multiple runs in. Do I need to keep making new accounts or is there some way to reset your progress? Let me know.
