Search for usages
When you write or edit code, you might come across a code element that you want to change or delete. Before you make the changes, it is a good practice to see where the code element is used and how it affects the application. With the Find Usages actions you can search for the references of your code element throughout the whole codebase.
You can manage the search process, and search only in a single file, extend your search to the whole project, or create a certain search scope. Moreover, you can configure the color of the usages highlighting or disable the automatic highlighting of usages altogether.

In the editor, select an element you want to find, RubyMine automatically highlights all found usages in the file. If the highlighting of usages is disabled, press Ctrl+Shift+F7 to highlight all usages in the file.
From the main menu, selectCtrl+F7. RubyMine selects the first usage occurrence in the file.
Use the F3 and Shift+F3 shortcuts to navigate between highlighted symbols.

Check the results in the Find tool window.
Show usages in a separate window
You can view usages of the selected symbol in a separate window that you can move to different parts of your screen and use for quick navigation.
In the editor, select a symbol for which you want to see the usages.
From the main menu, selectCtrl+Alt+F7.
The usages window shows the current scope and total count of usages. If you want to quickly switch to the default scope, press Ctrl+Alt+F7.
If the search results have too many entries, then RubyMine shows the first hundred usages found and the more usages option on the bottom of the window which you can click to display another hundred usages, and so on until the search is finished.
Use filters on the top of the window to show or hide the certain search entries.

If RubyMine doesn't return any results, it will display a message suggesting that you opt for more options.
You can follow the link or press Ctrl+Shift+Alt+F7 to open the Find Usages dialog again and set a new scope for your search.
