# Navigation Implementing navigation to resolved symbols or other PSI elements. > This API is available starting from 2020.3 and currently in development and thus in experimental state. > {style="warning"} The Navigate | Declaration or Usages action is performed in several steps. ## Direct Navigation Direct navigation is the navigation from `PsiElement` to another `PsiElement`, such as navigation from `break` keyword to the end of a loop in Java, without showing any popups. To provide `PsiElement` for direct navigation, implement and register [`DirectNavigationProvider`](%gh-ic%/platform/core-api/src/com/intellij/navigation/DirectNavigationProvider.java) in `com.intellij.lang.directNavigationProvider` EP. ## Symbol Navigation If there is no Direct navigation available under the caret, then the IntelliJ Platform proceeds with `Symbol` navigation. In this step the IntelliJ Platform computes the navigation targets based on target symbols, which it obtains by resolving a [reference](declarations_and_references.md#references). If there are several target symbols or several navigation targets defined for a symbol, then the IDE shows the navigation popup to ask the user to choose where to go. The [`NavigationTarget`](%gh-ic%/platform/core-api/src/com/intellij/platform/backend/navigation/NavigationTarget.java) is essentially a pair of a `Navigatable` and a [`TargetPresentation`](%gh-ic%/platform/core-api/src/com/intellij/platform/backend/presentation/TargetPresentation.kt) instances (where to go and what to show in the popup). To provide navigation targets by a `Symbol`, either: - implement and register [`SymbolNavigationProvider`](%gh-ic%/platform/core-api/src/com/intellij/navigation/SymbolNavigationProvider.java) in `com.intellij.symbolNavigation` EP; - or implement [`NavigatableSymbol`](%gh-ic%/platform/core-api/src/com/intellij/navigation/NavigatableSymbol.java) in the `Symbol`. ## Showing Usages If there are no navigation targets available, then the IntelliJ Platform starts finding usages of the target symbol obtained by resolving a [reference](declarations_and_references.md#references) or from a [declaration](declarations_and_references.md#declarations). > Existing implementations of the mentioned extension points can be found on the [IntelliJ Platform Explorer](explore_api.md#32-search-the-intellij-platform-explorer). > {style="note"}
