Short name
Most items and crew have two names, their short name and their full name.
Items
An item's short name is displayed when the item is acquired as a "Rare (one-time) Reward" or from the Dabo Wheel.
Often times items are sorted in-game by their short name rather than their full name (also by whether the item is a 1-time reward and by rarity).
Crew
Short name of crew members is called Character name. All crew members with the same short name are versions of each other. (Versions are most relevant in events). Note however that not all versions share the same short name–for example, Changeling Bashir is a version of Changeling, not Bashir. List of crew short (character) names.
The short name is displayed in crew selection, when used during missions, and when crew are acquired via the Time Portal.
