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 from the main menu. If you are using Windows, you can also press Ctrl+F3.

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

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.
Use bookmarks for navigation
To create an anonymous bookmark, place the caret at the needed code line and press F11.

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 dialog (Ctrl+Alt+S) , go to and clear the Show code lens on the scrollbar hover checkbox.
