If you hold down the R button you will reset after holding it for 3 seconds, you can change this in the menu > settings and right click the time to make it down to instantly reseting or left click it up to 10 seconds.

but zen, in (special) coils speedrunning, quick restarting takes time for items to load you know. plus, manually resetting back to the lobby takes a lot of time and i dont like that. so should i start the timer at the first frame of movement in a run?
