Takeoff clearance is definitely the selection of the "Takeoff" light on Airbus. On Boeing, I don't know what you might use, but for gods sake, choose one!
Small tip FWIW. I do the same, but I use spaces between the taxiways, and the slash for hold short, so "A B C1 /27L". I know it's unlikely you will use 27L to taxi, but I like the extra reminder.
