-nano does not completely emulate Pico by default.  The following
-differences apply to the default mode and Pico Compatibility mode:
+@code{nano} attempts to emulate Pico as closely as possible, but there
+are certain differences between the editors:

-By default, the following shortcuts are displayed in the Shortcut List:
-
-@multitable @columnfractions .1 .1 .1 .1 .1 .1
-@item ^G @tab ^O @tab ^\ @tab ^Y @tab ^K @tab ^C
-@item ^X @tab ^R @tab ^W @tab ^V @tab ^U @tab ^T

-
-Related functions are listed above or below each other by default.  The
-Justify function is not listed, instead the ``Replace'' function is
-displayed.  Also, the ``Read File'' and ``WriteOut'' functions are aligned
-for consistency.
-
-In Pico Compatibility mode, the default Pico shortcuts are displayed:
-
-@multitable @columnfractions .1 .1 .1 .1 .1 .1
-@item ^G @tab ^O @tab ^R @tab ^Y @tab ^K @tab ^C
-@item ^X @tab ^J @tab ^W @tab ^V @tab ^U @tab ^T
-@end multitable
-
-@item Previous String Text
-By default, the previously entered string for a function (search string,
-file name) will be placed on the statusbar, and is editable.  This is
-done so there is consistency across all functions.  For example: even if
-there is a previous replace string, it can always be deleted if one
-wishes to perform an empty string replace.
-
-In Pico Compatibility Mode, the previously entered text in a search or
-replace will appear in brackets, and is not editable.  It is not a
-simple matter to do an empty string replace when a previous replace
-string exists, for example.  When writing a file, the previous filename
-will be displayed in the editable text portion of the editor.
+@item Search and Replace History
+As of version 1.1.99pre1 of @code{nano}, text entered as search or replace
+strings will be stored and can be accessed with the up/down
+arrow keys.  Previously, @code{nano} offered a more consistent, but incompatible
+with Pico, method for entering search and replace strings.  In the old
+method, previous entries would be displayed by default as editable text 
+in front of the cursor, as opposed to being bracketed and uneditable as 
+it is in Pico.  The old behavior could be made compatible with Pico via the
+@code{-p} flag, but recent versions of Pico use the @code{-p} flag 
+to preserve the XON and XOFF sequences within the editor.  Since with the new 
+method search and replace strings can still be edited by simply hitting the 
+up arrow key once, the old method was removed completely.
+
+
+@item Writing or Appending Selected Text to Files
+Text selected using the Control-Caret (^^) key can be written out or
+appended to a new or existing file using the Writeout key (^O).
+
+@item Toggles
+Many options which alter the functionality of the program can be 
+"toggled" on or off using Meta key sequences, meaning the program does 
+not have to be restarted to turn a particular feature of the editor 
+on or off.  Please see the internal help function (^G) for a list of 
+what functions can be toggled for a particular version of 
+@code{nano}.
+
+@item Cursor Position Display
+The output of the "Display Cursor Position" in @code{nano} displays
+the given column position, as well as the row and total character
+position of the cursor.
