Click the Select arrow 
on the tool panel on the left to move, rotate or delete selected object(s) in the drawing.
You can change a constraint value, annotation or label by double clicking it, retyping the value or variable and then pressing the enter key.
The Scale, Zoom and Move / Pan functions have a mouse shortcut:
- The scroll wheel on your mouse can be used to Scale the drawing up or down. Hold down the ctrl key while moving the wheel and the operation becomes a Zoom.
- Right-click and drag the mouse anywhere in the drawing window to Move or Pan.
The Move geometry icon 
is a modal command. It stays active until you select 
or choose another mode (e.g. any Draw tool).
