I'm looking for a solution for creating short and clean screen casts for teaching programming. I want to be able to prepare my scripts in advance and then play them when recording (or directly converting to something i can put in a webpage). The best solution I've found to time is https://github.com/gu-fan/autotype.vim https://github.com/gu-fan/autotype.vim ... but in my tries it was flickering a bit too much. Does anybody know a good, lightweight and free software solution that allows to move the cursor during the editing?
