I'm missing something extremely obvious with Krita?!

Firstly, the programme always opens with the 'Freehand Brush Tool'. Well, that's OK. Not too big a problem.

However, my problem is, that after I've drawn something with the Freehand Brush Tool, I cannot now move the drawn shape to another part of the canvas.
What am I missing, that I haven't been able to work out how to do this simple task?
Someone. Please put me out of my misery!
