Map Control Panel 

Type MID as the city name, and click Find.  Also try: clicking on the version number, option-clicking on Find, opening the control panel while you hold down shift and/or option, clicking somewhere in the Map and dragging off the edge of it, or copying the map from the Scrapbook and pasting it while the Map control panel is open.

The stored point MID is actually "Middle of Nowhere", an insignificant location in the middle of the South Atlantic.  (This one was added in version 7.0.) Clicking on the "7.0" puts "v7.0, by Mark Davis" into the city name field until you release the mouse button. Option-clicking on Find repeatedly will take you alphabetically to every city the Map knows. Opening the control panel while you hold down the shift key will display a magnified map (the resolution is the same, so it's very jagged). Opening it with option held down magnifies it more, and shift-option magnifies it even more to the point of being really blocky. Dragging off the edge of the map will scroll around the world. You can paste a new picture into the control panel; the Scrapbook that comes with System 7 includes a particularly good color map. (Contributed by Takeshi Miyazaki and Doc O'Leary)
