PS CS4 supports ”Flick Panning”. While using the Hand tool to move left, right, up or down in an image (click, drag and hold for legacy behavior). Flick Panning does require Open GL and can be toggled off in the Preferences / General. While in the Preferences be sure to try Zoomed Click Point to Center which centers the location of the cursor click point to the center of the screen. And don’t forget, Option (Mac) / Alt (Win) + spacebar will temporarily give you the Zoom Out tool while another tool is selected while Command (Mac) / Control (Win) + spacebar will temporarily give you the Zoom In tool while another tool is selected.
