how to slew in a dungeon?

How do you enter slew mode?

 

i think it's supposed to be
/slew
but is not in yet

 

it IS in, but it's adv mode only, not deco mode

 

Tried it out. It works. Here's what i found so far:

/slew - begin slewing
w - move forward
s - move backward
a - left
d - right
q - down
e - up
esc - exit slewing mode
right-click mouse + movement - rotate angle

 

Is it planned to do this in deco mode? That seems to make more sense. While you're creating the dungeon, being able to slew around to see how everything fits. As it is now, you have to lay out some stuff, exit the dungeon, change modes, go back in, slew, go back out, change modes, go back in, make your changes.
