Highlights identifiers under caret. If more than one instance with the same identifier is used in the file, only the usages of that
specific instance are highlighted. For parameters, local variables, and fields, a differentiation between reads and writes to that identifier are made with separate configurable colors.
Use Shift+Alt+Up and Shift+Alt+Down to navigate up and down to each highlighted occurrence.
Use Shift+Alt+L and Shift+Alt+U to lock and unlock the highlighting to allow movement through the file without changing the highlighted occurences.
Use Shift+Alt+T to toggle the plugin on or off.
