-** Open BUGS **

-** Fixed BUGS **
-- Marked cutting sometimes leaves a newline in the file unintelligently,
-  such as when all of a line is selected but the mark doesn't proceed to
-  the new line. (8) [FIXED/IRRELEVANT]
-- Certains are not lined up properly when there are tabs in them at 
-  certain col values. (9) [FIXED]
-- edit_refresh() and update_line() do not handle selecting text when the
-  cursor is beyond COLS (10) [FIXED]
-- No way to do a replace with the empty string (11) [FIXED, yay!]
-- Spelling support is not elegant like Pico's integration of the 'spell'
-  program.  nano only uses ispell (for now) (12) [FIXED]
-- Moving to the end of a line when close to a multiple of COLS and at
-  least COLS * 2 does not make the screen jump early like it would for
-  if we were around COLS (bugs in edit_refresh, update_line) (13)
-  [FIXED, mostly]
-- When at the very bottom of the edit window, do_wrap() goes berserk and
-  puts the cursor somewhere bad; subsequent keystrokes crash the program
-  (14) [FIXED, mostly]
-- Doing a replacement of a substring of the replace string (e.g.
-  replacing "ed" with "fred" causes an infinite loop). (15) [FIXED]
-- Cutting a file with marked text and both marker ends on the same line
-  causes a random segfault (16) [FIXED]
-- Cutting more than one line resets the KEEP_CUTBUFFER flag in 0.9.3.
-  Error is in bitwise assignment (nano.h). (17) [FIXED]
-- The wrapping code does not work right for lines like the following:
- *                                                                     *
-  Error is in do_wrap, must be rewritten. (18) [FIXED]
-- nano fails to follow symlinks, even though -l isn't being used (20).
-  [Bug in global flag init, FIXED]
-- When using --help or --version, the SIGINT character gets lost. (21)
-  [FIXED]
-- edit_refresh() and update_line() (and related functions) have 
-  trouble when a tab is the character that is the boundary at COLS (23)
-  [FIXED]
-- There is an off-by-one error in keeping track of totsize.  It is
-  caused by the fact that we count the newline at the end when we read
-  in a file but we do not, in fact, display this newline.  This should
-  go away implicitly when the "Magic Line" returns, but it is noted here
-  for documentation's sake. (24) [FIXED]
-- In replace with completely adjacent strings, every other search string
-  will be missed (try replace ':' in a string like ':::::::::') (28)
-  [FIXED]
-- If nano opens a read-only file with the --tempfile option, and a
-  change is made to the buffer, and a write is attempted, nano will not
-  give you a dialog about not being able to write the file, and it will
-  not let the user exit (29, discovered by Joshua Jensen) [FIXED]
-- Using nano -k, marked text is not cut properly. (31) [FIXED]
-- Invoking -t or -k has the effect of invoking both options. (32)
-  [FIXED]
-- totsize becomes incorrect after word-wrapping (25) [FIXED]
-- Wrapping a line with autoindent mode sometimes causes a segfault (19)
-  [FIXED]
-- When inserting files, the display sometimes fails to display properly
-  until a pageup/down occurs (22) [FIXED]
-- In search/replace code, there is too much refreshing in bottomwin (26)
-  [FIXED]
-- In replace, there is no way to accept the default replace string. (27)
-  [FIXED]
-- Using nano -t, user can not exit until a filename is given via ^O.
-  (30) [FIXED]
-- totsize problems still abound in do_justify (33) [FIXED]
-- Using -k, cut text is not pasted properly. (34) [FIXED].
-- Using -k, pasted text is not updated properly if it goes beyond
-  editbot. (35) [FIXED]
-- Doing a cut with -k can screw up the filestruct; fault is in cutting
-  code. (36) [FIXED]
-- Hitting enter on the magic line makes new lines, but they are not
-  written out to disk when saved..... (37). [FIXED]
-- Page up and page down do not work the same way as in Pico (# of
-  lines). (38) [FIXED]
-- When doing a search and the marker is set, the screen does not always
-  properly update the inverted text (39). [FIXED]
-- Searches for a string that only exists on one line multiple times will
-  fail after finding the last occurrence (discovered by Ken Tyler) (40).
-  [FIXED]
-- Meta-Z is currently broken to toggle suspend.  I guess I still don't
-  know signals very well =-) (41) [FIXED].
-- Unable to cut the entire file using the marker (discovered by Ken
-  Tyler) (42). [FIXED]
-- The keypad does not work when nano runs in the Gnome terminal (43).
-  [FIXED]
-- When reading in a file, if the file is a directory, the contents of
-  the file being edited are blown away (discovered by  Chris Pimlot)
-  (44). [FIXED]
-- In certain terms, nano will leave a "ghost" of screen upon exit when
-  called from inside mutt (among other settings) (45). [FIXED]
-- In replace, hitting the Goto line shortcut key does nothing after a
-  search string is entered (discovered by Rocco Corsi) (46) [FIXED].
-- When typing in a string in search or replace and hitting
-  CASE_SENSITIVE or the other search string, the current string edit is
-  blown away in favor of the last stored search (47) [FIXED]
-- If nano fails to open a file when it starts up, doing almost anything
-  causes a segfault (discovered by Ben Roberts) (48). [FIXED]
-- In certain terminals, nano would not work properly with keypad().
-  Turned out to be the silly timeout(0) call, which is completely
-  unneeded, anyway. (49) [FIXED]
-- With less than a page of text, doing a page down will move the current
-  line to the top of the screen, which it shouldn't do. (50) [FIXED]
-- With PDCurses, running Meta-X turns off the keypad. (51) [FIXED]
-- Resizing the window completely screws up the display if in any other
-  mode than normal editing (help screen, search and replace, file
-  browser...) (52) [FIXED]
-- Alt speller argument (-s, --speller) does not take a string argument
-  of more than one word. (53) [FIXED].
-- Cut to end cutting (-k) causes segfaults (try cutting "- Backup making
-  (filename~)?" line in TODO file) (discovered by
-  higuita@cadernoverde.com) (54) [FIXED].
-- When using autoindent (-i), wrapped text does not get autoindented
-  (55, discovered by Mark Senior) [FIXED].
-- When using -R (regex) and -p (Pico mode), subsequent searches after
-  the first fail if no string is entered (56) [FIXED].
-- Page down on a file of editwinrows fails (again). Reported by Ryan
-  Krebs (57) [FIXED].
-- File browser aborts on Solaris in qsort() call. (Reported by Matthias
-  Andree) (58) [FIXED].
-- Can modify the current file in view mode with ^W^R (discovered by
-  Rocco Corsi) (58) [FIXED].
-- When page up is used after two page downs, the screen doesn't update
-  properly (discovered by David Lawrence Ramsey) (59) [FIXED].
-- On BSD systems, marked cutting and paste often screws up the last line
-  in the cutbuffer (discovered by Barry Pederson) (60) [FIXED]
-- Blank lines are not kept when cutting with -k (discovered by Rocco)
-  (61) [FIXED].
-- nano will not suspend properly inside of mutt (62) [FIXED].
-- When switching from Pico mode to normal mode, the previous search is
-  not displayed until cancelling the search (63) [FIXED].
-- If you change search options but don't change the search string in
-  normal mode, hitting Enter causes the search/replace to abort (64)
-  (Jordi Mallach) [FIXED].
-- Cutting one line of text causes the screen to recenter the line
-  (reported and fixed by David Lawrence Ramsey) (65) [FIXED].
-- When cutting marked text including the bottom of the file, a new
-  "magic line" is not created" (reported by David Lawrence Ramsey, fixed
-  by David Lawrence Ramsey & Chris) (66) [FIXED].
-- ^C does not work after a suspend in tcsh (discovered by Trevor Cordes)
-  (68) [FIXED].
-- Home and End control keys (^A, ^E) do not always work in filename
-  prompt (bug found by Ian Turner) (69) [1.0 series only] [FIXED].

 missing (or disabled by default) features in Pico, such as "search and
 replace" and "go to line and column number".
 
+.SH EDITING
+Entering text and moving around in a file is straightforward: typing the
+letters and using the normal cursor movement keys.  Commands are entered
+by using the Control (^) and the Alt or Meta (M-) keys.
+Typing \fB^K\fR deletes the current line and puts it in the cutbuffer.
+Consecutive \fB^K\fRs will put all deleted lines together in the cutbuffer.
+Any cursor movement or executing any other command will cause the next
+\fB^K\fR to overwrite the cutbuffer.  A \fB^U\fR will paste the current
+contents of the cutbuffer at the current cursor position.
+.PP
+When a more precise piece of text needs to be cut or copied, one can mark
+its start with \fB^6\fR, move the cursor to its end (the marked text will be
+highlighted), and then use \fB^K\fR to cut it, or \fBM-6\fR to copy it to the
+cutbuffer. One can also save the marked text to a file with \fB^O\fR, or
+spell check it with \fB^T\fR.
+.PP
+The two lines at the bottom of the screen show the most important commands;
+the built-in help (\fB^G\fR) lists all the available ones.
+The default key bindings can be changed via the .nanorc file -- see
+.BR nanorc (5).
