Source code navigation
You can quickly navigate through code in the editor using different actions and popups.
You can start with watching a video tutorial to check what navigation options are available in RubyMine.
Find a file path
In the editor, press Ctrl+Alt+F12 or in the context menu, select Reveal in Finder.
In the Reveal in Finder popup, select a file or a directory to open in a path finder and press Enter.
Navigate with the Select In popup

If the file is opened in the editor, press Alt+F1 to open the Select In popup.
In the popup, select Project View and press Enter. RubyMine locates your target in the Project tool window.
Use Autoscroll to locate a file
You can use the Autoscroll to Source and Autoscroll from Source actions to locate your file in the Project tool window.
In the Project tool window, right-click the Project toolbar and from the context menu select Autoscroll from Source. After that RubyMine will track the file that is currently opened in the active editor tab and locate it in the Project tool window automatically.
You can also select the Autoscroll to Source option. In this case, when you click a file in the Project view, RubyMine will automatically open it in the editor.
Use bookmarks for navigation
To create an anonymous bookmark, place the caret at the needed code line and press F11.
To create a bookmark with mnemonics, place the caret at the needed code line, press Ctrl+F11 and select a number or a letter for the mnemonics.
To show the next or the previous bookmark, press N/A or N/A respectively.
To open the Bookmarks dialog, press Shift+F11. You can use this dialog to manage bookmarks, for example, delete, sort bookmarks, or supply them with a brief description.

For a type declaration, press Ctrl+Shift+B.

In the popup, locate an item you need. You can start typing a name of the element for RubyMine to narrow down the search. Press Enter to return to the editor and the corresponding element.
Browse through methods
To visually separate methods in code, in the Settings/Preferences dialog (Ctrl+Alt+S), go to and select the Show method separators option.
Use the Lens mode
The lens mode lets you preview your code without actually scrolling to it. The mode is available in the editor by default when you hover your mouse over the scrollbar.
To disable the lens mode, right-click the code analysis marker located on the right side of the editor and in the context menu clear the Show code lens on the scrollbar hover checkbox.
As an alternative, in the Settings/Preferences dialog (Ctrl+Alt+S), go to and clear the Show code lens on the scrollbar hover checkbox.
Use breadcrumbs for navigation
You can navigate through the source code with breadcrumbs that show names of classes, variables, functions, methods, and tags in the currently opened file. By default, breadcrumbs are enabled and displayed at the bottom of the editor.
To change the location of breadcrumbs, right-click a breadcrumb, in the context menu select Breadcrumbs and the location preference.

Double-click the selected file, or press Enter to open it in the editor.
Find a line or a column

You can also select a text and then move the caret forward or backward to a paragraph. Press Ctrl+Shift+A and search for the Move Caret Forward a Paragraph with Selection or Move Caret Backward a Paragraph with Selection action.
If you need, you can assign shortcuts to these actions. Refer to Configuring keyboard shortcuts for details.
