Most general-purpose editors come with a variety of presets to make tagging more accessible to new mappers or more efficient to experienced mappers. Each preset automatically applies primary feature key or tag to a feature, potentially along with one or more secondary tags for more specificity. A preset may also come with a dedicated UI with fields for common values or related keys. In some editors, a preset also determines how the editor renders the feature on the map canvas.
Presets have not been standardized across editors and generally are not documented on this wiki's key and value description pages, but taginfo's Projects tab shows which presets use a given key or tag in each editor.
Presets by editor
Presets are the main way that users add tags to a feature in iD, though they are labeled feature types in the UI. You choose a feature type after drawing the feature.
MAPS.ME has a fixed selection of POI types.
In Potlatch 1, the tag list panel also contained a dropdown menu for choosing from "presets" that were essentially human-readable names for feature tags.
StreetComplete is a more directed editor that does not generally allow the user to map arbitrary features. However, it uses iD presets via osmfeatures to describe a task in terms of a feature type in the user's language.
The Overpass turbo query wizard recognizes queries of the form "preset" (in double quotation marks), where preset is the name of an iD preset in American English, so someone can easily query OpenStreetMap without necessarily knowing the specific tag they are looking for.
