Installation

USE flag (what is that?) Default Recommended Description

minimal No No Disable all fancy features, including ones that otherwise have a dedicated USE flag (such as spelling).

Usage

First steps

Start nano by typing in your terminal nano followed by options. The most common option is a file name and path, e.g.:

user $nano filename

Nano now shows the content of the text file and you can edit the file. Navigate through the text with the arrow keys.

At the bottom nano shows shortcuts for common actions, e.g. save or exit. The shortcut to save is shown as "^O". You have to prefix the shortcut with the Ctrl key, so to save press Ctrl+O. To exit press Ctrl+X.

Important
To edit configuration files always use the -w option. Without that option long lines are wrapped and, when saving, are saved wrapped. This breaks your config files.

To see an overview over all options run nano --help.

Cut, Copy and Paste

You can cut a line with the shortcut Ctrl+K (copy with Alt+^) and paste it with Ctrl+U. To cut / copy multiple line also press the shortcut multiple times.

Search

Search the text with Ctrl+W. Continue the search with Alt+W.
