I've recently re-remapped my tilde/backtick to Escape (that's how at least I originally learned) and put the tilde/backtick in the left-Windows key (again how I originally learned).
That floating Esc
key way up in the NorthWest now, I've thought about mapping it a copy of F9 (for a generic SQL execution key). Is there a suggested use for the floating Escape key that can assist a programmer?
