 ## Misc Improvements
 - Init scripts: ``dfhack.init`` and other init scripts have moved to ``dfhack-config/init/``. If you have customized your ``dfhack.init`` file and want to keep your changes, please move the part that you have customized to the new location at ``dfhack-config/init/dfhack.init``. If you do not have changes that you want to keep, do not copy anything, and the new defaults will be used automatically.
+- `keybinding`: support backquote (\`) as a hotkey
 - `manipulator`: add a library of useful default professions
 - `manipulator`: move professions configuration from ``professions/`` to ``dfhack-config/professions/`` to keep it together with other dfhack configuration. If you have saved professions that you would like to keep, please manually move them to the new folder.
 - ``materials.ItemTraitsDialog``: added a default ``on_select``-handler which toggles the traits.
