+For numeric fields: :code:`id`, :code:`pid`, :code:`num` and :code:`recent`, the expression is interpreted as
 a number, not a regular expression.
+
 The field :code:`num` refers to the window position in the current tab, starting from zero and counting clockwise (this
 is the same as the order in which the windows are reported by the :italic:`ls` command).
+
 The window id of the current window is available as the :envvar:`KITTY_WINDOW_ID` environment variable.
+
 The field :code:`recent` refers to recently active windows in the currently active tab, with zero being the currently
 active window, one being the previously active window and so on.
+
 When using the :code:`env` field to match on environment variables, you can specify only the environment variable name
 or a name and value, for example, :italic:`env:MY_ENV_VAR=2`.
+
 The field :code:`state` matches on the state of the window. Supported states are:
 :code:`active`, :code:`focused`, :code:`needs_attention`, :code:`parent_active` and :code:`parent_focused`.
 Active windows are the windows that are active in their parent tab. There is only one focused window and it is the
 window to which keyboard events are delivered.

 Note that you can use the :ref:`kitty @ ls <at_ls>` command to get a list of windows.
