Yes, tom, there is a key assigned for this. Just check game options - controls to see what it is by default and change it to some other key if you want.
As for the tutorial area, i would also suggest that it doesnt give any xp or loot.
Since if it does it becomes almost mandatory for most players since they will feel they are missing out. Even if the amounts are minimal and loot hardly worth the bother.
Or there could be an option to go inside and skip it, being teleported to the exit with all xp and loot.
Best case scenario would be to make a separate tutorial outside of the game and turn that dungeon into something a bit more interesting.
