Is there an option to change how a block moves?

The block below (made with a lot of unions) seems to only move diagonally. How do I change that? Is there an option for that?

Please also reply if you are certain there is no feature for this!

If you mean in studio, press Control + L.

Ctrl-L what? is something supposed to pop-up? Not seeing anything :confused:

Edit: Oh I get it now Thanks!
