Keyboard shortcuts are designed to ease your life so you don’t have to remember a lot of shit, but I can never seem to remember them. I guess I like typing a lot more than I care to admit. But I do need to be more productive, so I sort-of-commit today to learn at least a few keyboard shortcuts every day. I’ll start with Nano since its nano (get it?). I’ve divided up the shortcuts into categories so I can recall them more easily.

But first, a little history. Nano started life as a free replacement for the Pico text editor. And that’s about it, really. It’s pretty simple to use and powerful-enough that you should be able to do pretty much anything, but for more power and control use Vi.

So here we go. Control-key sequences are notated with a caret (^) symbol and can be entered either by using the Control (Ctrl) key or pressing the Escape (Esc) key twice. Escape-key sequences are notated with the Meta (M-) symbol and can be entered using either the Esc, Alt, or Meta key depending on your keyboard setup. Alternative keys are shown in parentheses.
