Emacs handy commands
In this post I will briefly touch upon some of the handy commands that can help new Emacs users like myself to have a smoother transition to Emacs and easier adoption and integration of it in to their workflows. The aim is NOT to teach Emacs, but it is to mention things that took me hours of searching to find online. I'll update this blog post every now and then to add more content instead of creating new blog posts. This would make this blog post a one-page cheatsheet for myself and others.
