Xah Emacs Demo 2018-05-26 📺
Working in emacs real time. This one also shows command-log-mode.el
there is lots emacs tutorials, or demo of emacs packages. Those are usually prepared, condensed, teaches you something, very nice.
one problem is that you don't see how people actually work in emacs. e.g. all the fumbling, and or workflow.
so, i think some real time emacs use is fun to watch. e.g. when you heard about a package, how do people go about installing it and make it work.
