How to move around in Halo editing kit/sapien

Hey everyone. I know this is kind of weird to ask as this is a Halo Custom Edition question. I got Sapien, the halo 1 map editor program to work. I can move around in it in the sense of moving forward, backward, and sideways, but I don’t know how to move upward or downward. Would appreciate the help. Thanks!

Ok, never mind. I managed to figure it out. I’ll leave this up here incase anyone else is trying to figure out Sapien in 2020.

Controls:
Hold down the scroller of your mouse (aka mouse 3)
W- moves forward
S - moves backward
A - move to the left
D - move to the right
R- move up
F - move down
Mouse - look around/steer
SHIFT - increase speed

Here is a link to some general stuff you can do in Halo Custom Edition as well:

The controls are something the tutorials seem to not talk about so I hope this helps anyone!
