I am going to be making a presentation in sometime. The presentation would have multiple lines in one page and there are going to be few pages of the presentation.
Now I want each line in a page to appear when I click Spacebar on the lappy, something like/similar to what Bradley Kuhn has done in http://meetings-archive.debian.net/pub/debian-meetings/2016/debconf16/The_Supreme_Court_of_DFSGFree.webm . I am sure there are many other examples as that presentation.
How do people do it ?
