I am a bit embarrassed to confess how long I have been using pymol for. It’s certainly been quite a long time, somewhere around ten years. In those years I’ve compiled my own cheat-sheet, which I have abandoned somewhat. Now I’m giving a go to markdown and translating my old cheat sheet into a new one but with the same old tricks.
