The difference between micro and nano is that nano's keyboard shortcuts are pretty opinionated, while micro's are the ones used by most (GUI) applications nowadays: Ctrl+S for saving, Ctrl+F for find, Ctrl+Z for undo, Ctrl+Q to exit etc. etc. There is also a helpful hint at the bottom of the screen that you can press Alt+G to see the shortcuts, or Ctrl+G for some help.
