Click-drag the selection tool (see red box below) to move in a more controlled fashion through the data. Choose the selection tool (default tool) and then click anywhere near the edge of the image. Keep the mouse pressed and drag the cursor (arrow) to the left or right. The display will continue moving at a steady pace for as long as the click-drag is held. This click-drag interaction is similar to how you can scroll up or down in many word processing programs, where you can select text and then drag the cursor up or down to scroll through the document.

This new feature debuted in IGB 6.5. Here, you select the Grab tool ("cartoon hand") and click it within the display. Use it to drag the display in the direction you want to move.This is the opposite direction from click-drag movement, and can be more intuitive to some users. It also moves at the speed that the user moves the mouse, whereas click-drag moves at a steady pace. On the other hand, grab-drag can only move the image to the edge of the main window. You must re-grab to continue moving.
This form of movement can also be used to shift the image vertically if the vertical zoom is active.

Resolution reflects the zoom level of the image. This can be set by hand, or just left 'as is' if you have already gone to the zoom level you prefer. Scroll increment is how far it shifts distance (in pixels) the image shifts each time it moves; Time interval is how fast the speed at which the image moves. These three elements work together to affect the final scrolling speed at which you see data move pastof your data at your chosen zoom level. We recommend setting the zoom level based on the image, then adjust the time or scroll until it is moving at a level comfortable for you. Megabases per minute and Total minutes for seq. will give you an idea of the final Autoscroll speed.
