I have a document that I would like to hide part of a point of a star behind something else. I am not sure what the correct terminology would be or I would look it up online as I am sure there is a youtube video about it. I have a blue background with a grey border. One the blue background I have a white star and I want some of the star hidden behind the gray border, if that makes any sense. 

Any help is greatly appreciated. 

Thanks

You can make the shape with the grey stroke and blue fill (given it´s one object) a so called "Clip Group" by selecting and rightclick->Set Clip Group - now arrange in Objects and Layers tab as in the gif:

If that´s not an option as it propbly don´t work in a web-browser you can duplicate the shape and select with the star and go Path->Intersection.

Maybe all you need is to change the z-order or stacking order. With the Select tool [s], select the shape you wish to conceal then [Object > Lower to Bottom] . There's also a button in the tool control bar with the hint  [Lower selection to bottom].

Thanks a bunch, I got it the way I wanted it to go.
