Created attachment 142492 [details] Spreadsheet with audio and media files Spreadsheet with nserted media files, audio plus video are not showed on the navigator. It makes impossible to select when they are in background.
Click on the "Select" tool in the Drawing toolbar. That is the white arrow at the left side of the toolbar. Then click on the object, which is in background. Video and Audio are handled same as all other drawing objects in Calc. So the problem is not only with video and audio. We might consider to generate names automatically for drawing objects in Calc, same as it is done in Writer. I have not searched, whether such request exists already.
Thanks it works with the 'Select' of Drawing toolbar, but as commented having all kind of objects with the Navigator tdf#89528 would be nice. It happens also with pivot tables.
