 Improved terminal support
 -------------------------
 - OSC 133 prompt markers now also mark the prompt end, which improves shell integration with terminals like iTerm2 (:issue:`11837`).
+- Operating-system-specific key bindings are now decided based on the :ref:`terminal's host OS <status-terminal-os>`.
 - New :ref:`feature flag <featureflags>` ``omit-term-workarounds`` can be turned on to prevent fish from trying to work around incompatible terminals.
