nano: Entering Text
3.2 Entering Text
=================
‘nano’ is a "modeless" editor. This means that all keystrokes, with the
exception of Control and Meta sequences, enter text into the file being
edited.
Characters not present on the keyboard can be entered in two ways:
• For characters with a single-byte code, pressing the Esc key twice
and then typing a three-digit decimal number (from ‘000’ to ‘255’)
will make ‘nano’ behave as if you typed the key with that value.
• For any possible character, pressing ‘M-V’ (Alt+V) and then typing
a six-digit hexadecimal number (starting with ‘0’ or ‘1’) will
enter the corresponding Unicode character into the buffer.
For example, typing ‘Esc Esc 2 3 4’ will enter the character "ê" —
useful when writing about a French party. Typing ‘M-V 0 0 2 2 c 4’ will
enter the symbol "⋄", a little diamond.
