Pico is designed to be a simple, easy-to-use text editor with a layout very similar
to the pine mailer.  The status line at the top of the display shows pico's
version, the current file being edited and whether or not there are
outstanding modifications that have not been saved.  The third line from the
bottom is used to report informational messages and for additional command input.
The bottom two lines list the available editing commands.  Each character typed is automatically inserted into the buffer at the
current cursor position.

Editing commands and cursor movement (besides arrow keys) are given to pico
by typing special control-key sequences.  A caret, '^', is used to denote
the control key, sometimes marked "CTRL", so the CTRL-q key combination is
written as ^Q.

The following functions are available in pico (where applicable, c orresponding
function key commands are in parentheses).
 

    ^G(F1)       Display help text.
    ^F(->)       Move Forward a character.
    ^B(<-)        Move Backward a character.
