Highlight usages
The search command Control+Shift+F7 makes it possible to visualize usages of a symbol in the current file.
All found usages of a symbol in the current file are highlighted and color-coded, as defined in the Color Scheme settings page, to represent read or write access to the symbol. In addition to the highlights of occurrences in a text, the stripes of the same colors appear in the marker bar, accompanied by tooltips.
The behavior of usage highlighting is configurable: you can make PyCharm show usages of a symbol at caret automatically, or invoke it with a command.
