The search command Highlight Usages in File (Ctrl+Shift+F7) makes it possible to visualize usages of a symbol in the current file. In particular, it is possible to highlight implemented methods of interfaces. All found usages of a symbol in the current file are highlighted and color-coded, as defined in the Colors and Fonts settings page, to represent read or write access to the symbol. In addition to the highlights of occurrences in text, the stripes of the same colors appear in the marker bar, accompanied with tooltips.
The behavior of usage highlighting is configurable: you can make IntelliJ IDEA show usages of a symbol at caret automatically, or invoke it with a command.
This section describes how to:
- configure highlight usages behavior
- highlight usages
- highlight implemented methods
- navigate among usages
- remove highlighting
