The contact map also shows black dots when segments are actually in contact. Generally, two segments come into contact when they're less than 8 angstroms (8 band length units) apart. Different pairs of amino acids have different contact distances. The contact map is available on certain Foldit puzzles, which generally have "predicted contacts" in their titles. The contact map is displayed by the "Contact Map" button on the Actions menu in the original interface, or the Main menu in the selection interface. There is no keyboard shortcut for the contact map.
