recentering the mind map

hi … i am building my first ever mind map. is there a way to give me more space at the ‘top’ of the canvas? or, a way to re-center the whole map ‘further down’ the canvas? or, do i have to just begin again … and re-key my content in again further down the canvas … thank you …

Edit - Select all, and simply move it.

oh … that was easy! thank you. simple but i really do appreciate it!
