Use this tool if you work in a zoom view where you cannot see the complete page content. Once you have selected the Move tool, the mouse cursor is a hand which can be used to easily move the visible document area in the document window.
Press [Space bar] for activating the Move tool temporarily in any situation (except during the text edit mode). Then when you release the [Space bar], the previously selected tool will be re-activated.
Tip: You can optionally move the visible document area by using the window sliders or the Navigator inspector.
