- Main nano help text
- The nano editor is designed to emulate the functionality and ease-of-use of
- the UW Pico text editor. There are four main sections of the editor. The top
- line shows the program version, the current filename being edited, and whether
- or not the file has been modified. Next is the main editor window showing the
- file being edited. The status line is the third line from the bottom and
- shows important messages. The bottom two lines show the most commonly used
- shortcuts in the editor.
- The notation for shortcuts is as follows: 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. Also, pressing Esc twice and then
- typing a three-digit decimal number from 000 to 255 will enter the character
- with the corresponding value. The following keystrokes are available in the
- main editor window. Alternative keys are shown in parentheses:
- ^G (F1) Display this help text
