Breadcrumbs
-----------

At the top of the source listing, breadcrumbs for the file is shown.

You can select different tree from the repository drop down menu there, and also navigate to other directory, or open a context menu for the file symbol.

Line numbers
------------

Lines can be selected by clicking, optionally with modifier keys.  The selected lines are reflected to the URL, and opening URLs with those lines shows the selected lines.

This is handy for sharing a code with pointing specific lines.

  * Click the line number selects the line.
  * :kbd:`Shift` + click: selects lines by start/end range.
  * :kbd:`Ctrl` + click / :kbd:`Cmd` + click: adds/removes individual line from/to the selection.

Blame strip
-----------

See the :ref:`Blame strip <searchfox-blame-strip>` documentation.

Code coverage
-------------

The light-blue line next to the blame strip shows the `code coverage <https://firefox-source-docs.mozilla.org/tools/code-coverage/index.html>`__ information.

Hovering a pointer over the coverage strip shows a coverage popup, which shows how many times the line is hit in the automation.

For nesting structures inside a source code, such as namespaces, classes, functions, etc, Searchfox shows a sticky header for the nesting.

Symbols
-------

Clicking each symbol (functions, variables) opens :ref:`Context menu <searchfox_context_menu>`.
