nano is arguably the editor with the lowest learning curve. It is much younger than emacs and vi and was designed to replace pico. When you launch this editor with the command:
nanoif you get an error when you type that. Install the software by running
sudo apt -y install nanoyou will notice at the bottom a short list of common commands needed to edit documents. All of them are preceded by the ^ symbol which represents the ctrl key.

All the editors are powerful enough and I recommend familiarizing yourself with the one that makes the most sense to you. Finding out what works best for you will take a while and mastering it even longer if ever.
