Emacs facilitates looking up items in a dictionary, programmer's manual, or any similar list. The search results appearing in an Emacs buffer can then be transformed or reorganized.
Wikipedia:Lookup notes that "In computing, lookup usually refers to searching a data structure for an item that satisfies some specified property."
 Operational schemes
Here "dictionary" can mean any list of items, including programmer's manuals.
Note that "sends a query" could be as simple as a keystroke sending a character at point or region.
- Emacs searches local dictionary and displays results in a buffer
- Emacs sends a query to another program (dictionary server) on the same machine, and displays results in a buffer
- Emacs sends a query over a network and displays results in a buffer
- Emacs sends a query to another program (dictionary server) on the same machine, but results are in another program, not an Emacs buffer
- Emacs sends a query over a network, and results are displayed in another program (e.g. web browser tab)
The edict.el package searches for character at point or a region in a local dictionary such as Edict or Kanjidic, and displays results in a buffer.
