Are you absolutely sure you want all this code to run on every keystroke?

+        var zoomOutKey = WebInspector.KeyboardShortcut.makeKey(WebInspector.KeyboardShortcut.Keys.Minus.code, WebInspector.KeyboardShortcut.Modifiers.CtrlOrMeta);
+        var key = WebInspector.KeyboardShortcut.makeKeyFromEvent(event);
+        if (key === zoomInKey || key === zoomOutKey)
+            event.stopPropagation();
+    }
+    document.addEventListener("keydown", stopEventPropagation, true);
 }
