I'd like to place stuff around my houses but I don't know how to move things.

People told me to hold the use key over things I want to move. I try this. It doesn't work.

People told me to hold the use key and the Shift key over things I want to move. I try this. It doesn't work.

WILL SOMEBODY PLEASE TELL ME HOW TO MOVE STUFF?

Thank you.

Hold the use key.
