I notice that presentations have the input cells (the ones with code) often hidden. Specifically in slide shows. This seems like a pretty basic question, but I can't seem to find out how to do this. I need to put together a presentation and show a bunch of results. This is for non-Mathematica users and the code will just make things look unnecessarily confused. When I double click on an input cell bracket it will hide the output cell. If I have sections, subsections, etc., I can do the same thing. I don't know how to hide the complicated code in a presentation.
