If you click over an object with the left mouse button when you are in the layout window, a group of tooltip menu buttons (related to that object) will appear, as you can see in this image.
The first button starting from the left (
) allows you to start moving the pointed object.
It is the same command you can find by clicking the right mouse button, and select the command: Move.
Click ESC keyboard button if you want to exit this command.
If you have done the wrong modification on the element, click Ctrl + Z (UNDO) keyboard buttons together in order to roll back the last operation.
