5.3 Sub-Menus
Certain keys cause a sub-menu to appear where the adjustments can be made. These keys are ZOOM, POSITION/PAN, SIZE/EXPAND, VIDEO SETTINGS, MAGNIFIER, OPTION, and ABOUT. Wherever the arrow and number keys appear, their function is just like the remote control. The upward facing arrow at the lower right returns to the main menu.
