Code navigation

You can quickly navigate through code in the editor using different actions and popups. For the detailed information on navigating between the editor and tool windows, check the editor basics.

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 Up and Down arrow keys.

  • 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 to the code block start, press Ctrl+[, with the caret anywhere inside the code block. If the caret is already at the opening brace, press Ctrl+[ to jump to the start of the higher code block.

  • To navigate to the code block end, press Ctrl+], with the caret anywhere inside the code block. If the caret is already at the closing brace, press Ctrl+[ to jump to the end of the higher code block.

  • 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, AppCode 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 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.
