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.
Search for usages in a file
In the editor, select a symbol you want to find, GoLand automatically highlights all found usages in the file. If the highlighting of usages is disabled, press Control+Shift+F7 to highlight all usages in the file.
From the main menu, select Control+F7. GoLand selects the first usage occurrence in the file.
Use the F3 and Shift+F3 shortcuts to navigate between highlighted symbols.
Search for usages in a project
Select a symbol for which you want to find usages, right-click the symbol, and select from its context menu or press Alt+F7. When you press (Alt+F7), GoLand looks for usages of interface methods. To find usages of the current method, press Control+Alt+Shift+F7.
Check the results in the Find tool window.
If you need, you can group (
) the results by files, packages, directories, and so on.GoLand analyzes search results, detects the most common usage patterns, and categorizes all found usages into groups based on their structural similarity. These usage clusters appear in the Preview tab.
You can select any group node from the list and click Show similar usages to look through the results.
To disable this functionality, unselect the Enable similar usages clustering in Find Usages view in the advanced settings.

In the Find tool window, click the Preview Source icon.
As an alternative, you can select Jump to Source if you invoke the context menu on a usage found or Show in Split. In this case, the file with the result usage is opened in the editor.
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, select Control+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 Control+Alt+F7.
If the search results have too many entries, then GoLand 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.
View recent usages search results
GoLand remembers your Find Usages results, so you don't need to run the action again.

You can also set a custom scope by clicking
. For example, you can create a custom scope to exclude certain files from the search for usages, such as test files. When you are done setting a new scope, click Find.If GoLand doesn't return any results, it will display a message suggesting that you opt for more options.
You can follow the link or press Control+Alt+Shift+F7 to open the Find Usages dialog again and set a new scope for your search.

From the options on the right, open the node and select Identifier under caret.
In the Background field, specify the color you need and save the changes.
Search for the base method or method's implementations

If you select the Remember, don't ask again checkbox, GoLand will no longer display the prompt, and the selected search option will be used as default. If necessary, you can restore the prompt.
