# Matching

An object within the Editor Window can match to a pattern within its corresponding Palette Window. In other words, a molecule may match a molecular type within the Molecule Template Palette, a grouping of molecules may match a template grouping within the Species or Observables Palettes, or a reaction rule may match a template rule within the Reaction Rule Palette. Matching corresponds to either an exact match between two object names, or between objects where one is named and the other is a wildcard. In either case, matching also connotes structural equivalence between the involved objects where said objects may be components, molecules, species or reaction rules.

Matching may also occur within component states. Identically named states for two components will match, as will a named state and a wildcard.
