Code navigation

Navigate with the caret

• To navigate backwards, press Ctrl+Alt+Left. To navigate forward, press Ctrl+Alt+Right.

• To navigate to the last edited location, press Ctrl+Shift+Backspace.

• To find the current caret location in the editor, press Ctrl+M. This action might be helpful if you do not want to scroll through a large file.

  However, you can press the Up and Down arrow keys to achieve the same result.

• To highlight a word at the caret you are trying to locate, select Edit | Find | Next Occurrence of the Word at Caret from the main menu.

• To see on what element the caret is currently positioned, press Alt+Q.

• To move caret between matching code block braces, press Ctrl+Shift+M.

• To navigate between code blocks, press Ctrl+[ or Ctrl+].

Move the caret

You can use different actions to move the caret through code. You can also configure where the caret should stop when moved by words and on line breaks.

• To move the caret to the next word or the previous word, press Ctrl+Right or Ctrl+Left.

  By default, RubyMine moves the caret to the end of the current word.

  When you move the caret to the previous word, the caret is placed in the beginning of the current word. You can configure the position of the caret when you use these actions.

  In the Settings/Preferences dialog (Ctrl+Alt+S), go to Editor | General. In the Caret Movement section, use the When moving by words and Upon line break options to configure the caret's behavior.

• To move the caret forward to the next paragraph or backward to the previous one, press Ctrl+Shift+A and search for the Move Caret Forward a Paragraph or Move Caret Backward a Paragraph action.

  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 Configure keyboard shortcuts for details.

Find recent locations

You can also check your recently viewed or changed code using the Recent Locations popup.

• To open the Recent Locations popup, press Ctrl+Shift+E. The list starts with the latest visited location at the top and contains code snippets.

  

• While in the popup, use the same shortcut or select the Show changed only checkbox to see only the locations with changed code.

• To search for a code snippet, in the Recent Locations popup, start typing your search query. You can search by the code text, filename, or breadcrumbs.

  

• To delete a location entry from the search results, press either Delete or Backspace.

  Keep in mind that the deleted location is also removed from the list of entries that you access with the Ctrl+Alt+Left shortcut.

Go to declaration and its type

• Place the caret at the desired symbol and press Ctrl+B.

  Alternatively, use Ctrl+Click: keeping Ctrl pressed, hover your mouse pointer over the symbol. When the symbol turns into a hyperlink, its declaration will be displayed in the tooltip. Click the hyperlink without releasing the key to open the declaration in the editor.
