The traditional remapping for esc is pressing alt, because the alt key sends the escape key in terminals. Being able to fiddle with your keyboard layout is part of the fun of mechanicals, I happen to have this remapped at the OS level, because even on a laptop keyboard (yes I have a physical escape key) it's more convenient 90% of the time to press left Alt than the reach my pinky all the way up into Esc land.
