Moving the selection tool

How do you move the selection tool further along the track you’re working on than is shown in the window? Do you have to zoom out so as to see the whole track? Can’t you just push the right or left edge of the track to move the tool to where you want it on the track?

Zooming is one way - or if you want to retain your current zoom level used the horizontal scroll bar just below the bottom edge of the tracks pane.
