GNU nano is an easy to use text editor with additional functionality. nano will be installed by default, because it is the first "one of many" dependency of the virtual/editor package, which is part of the system set. It can be easily replaced with another text editor.

emerge --ask app-editors/nano
Start nano by typing nano in a terminal followed by options or a file. Passing a file name is the most common use:
Nano now shows the content of the text file and which can be modified as desired. 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. Prefix the shortcut with the Ctrl key. So to save a document (after editing it) press Ctrl+O. To exit press Ctrl+X.
Prior to nano 4.0, when editing configuration files, always pass nano the
-woption. Without this option, long lines are wrapped by inserting newlines - this will often break configuration files.
To see an overview over all options run nano --help
Cut, copy, and paste
Lines can be cut with the shortcut Ctrl+K (copied with Alt+^) and paste with Ctrl+U. To cut or copy multiple lines press the shortcut multiple times.
Search the text with Ctrl+W. Continue the search with Alt+W.
|Show the help||Ctrl+G||F1|
|Copy line to clipboard||Alt+^||Alt+6|
|Cut line to clipboard||Ctrl+K||F9|
|Paste line from clipboard||Ctrl+U||F10|
Set options permanently in the /etc/nanorc configuration file. This configuration applies system wide to all users. To change options only for one user, set the option in the user's ~/.nanorc file. As a general rule, files present in a user's home directory override system wide settings.
Support for syntax highlight is achieved through plugins and include statements in nano's configuration file (~/.nanorc for individual users).
Copy the plugin into the ~/.nano directory, then reference it with a include statement. For example:
# Ebuild specific highlighting include "~/.nano/gentoo.nanorc"
