I assume you're referring to the presets in iD. If that's the case, here are the tags that are applied by each preset:
Pedestrian Crosswalk: highway=crossing + crossing=zebra
Street Crossing: highway=crossinghighway=crossing
These tags can be seen by selecting the preset and then expanding the "All tags" section.
