+Hotkeys
+=========
+
+This page lists global Bonsai hotkeys.
+
+There are more hotkeys but they're tied to specific tools (e.g. Multi Object Tool, Annotation Tool, etc).
+They can be found in the UI when tool is selected.
+
+
+Blender Hotkeys Overrides
+-------
+
+As IFC objects are special in Blender, there are some IFC operators that repeat Blender functionality,
+but ensure the changes are in sync with IFC.
+
+IFC operators should be preferred always over Blender operators, when working with IFC project.
+
+For convenience, related hotkeys are overridden using their IFC versions.
