+# Custom default editor
+If you'd like to for example open #emacs with `-nw` you need to do some trickery.
+
+Create a script to open the editor and set it executable
+``` sh title="/usr/local/bin/emacs-nw"
+#!/bin/sh
+emacs -nw "$@"
+```
+
+Add the script to list of known editors (if using update-alternatives system) and set it default:
+``` console
+$ sudo update-alternatives --install /usr/bin/editor editor /usr/local/bin/emacs-nw 2;
+$ sudo update-alternatives --config editor;
+```
+
+You may also set variables in `~/.bashrc` like so:
+``` sh title="~/.bashrc"
+export VISUAL="emacs"
+export EDITOR="emacs -nw"
+```
