+@section Calculations in tables
+@cindex calculations, in tables
+
+The table editor has some spreadsheet-like capabilities. The Emacs
+@file{calc} package is required for this feature to work. There are
+basically two levels of complexity for table calculations in Org-mode.
+On the basic level, tables do only horizontal computations, so a field
+can be computed from other fields @emph{in the same row}, and Org-mode
+assumes that there is only one formula for each column. This is very
+efficient to work with and enough for many tasks. On the complex
+level, columns and individual fields can be named for easier
+referencing in formulas, individual named fields can have their own
+formula associated with them, and recalculation can be automated.

+@node Formula syntax, Column formulas, Table calculations, Table calculations
+@subsection Formula syntax
+
+A formula can be any algebraic expression understood by the Emacs
+@file{calc} package. Before evaluation by @code{calc-eval}
+(@pxref{Calling Calc from Your Lisp Programs,calc-eval,Calling calc
+from Your Lisp Programs,calc,GNU Emacs Calc Manual}), variable
+substitution takes place:
+
+@example
+ $ @r{refers to the current field}
+ $3 @r{refers to the field in column 3 of the current row}
+ $3..$7 @r{a vector of the fields in columns 3-7 of current row}
+ $P1..$P3 @r{vector of column range, using column names}
+ &2 @r{second data field above the current, in same column}
+ &5-2 @r{vector from fifth to second field above current}
+ &III-II @r{vector of fields between 2nd and 3rd hline above}
+ &III @r{vector of fields between third hline above and current field}
+ $name @r{a named field, parameter or constant}
+@end example
+
+The range vectors can be directly fed into the calc vector functions
+like functions @samp{vmean} and @samp{vsum}.
+
+@samp{$name} is interpreted as the name of a column, parameter or
+constant. Constants are defined globally through the variable
+@code{org-table-formula-constants}. If you have the
+@file{constants.el} package, it will also be used to resolve
+constants, including natural constants like @samp{$k} for Planck's
+constant, units like @samp{$km} for kilometers. Column names and
+parameters can be specified in special table lines. These are
+described below, see @ref{Advanced features}.
+
+A formula can contain an optional mode string after a semicolon. This
+string consists of flags to influence calc's modes@footnote{By
+default, Org-mode uses the standard calc modes (precision 12, angular
+units degrees, fraction and symbolic modes off). However, the display
+format which has been changed to @code{(float 5)} to keep tables
+compact. The default settings can be configured using the variable
+@code{org-calc-default-modes}.} during execution, e.g. @samp{p20} to
+switch the internal precision to 20 digits, @samp{n3}, @samp{s3},
+@samp{e2} or @samp{f4} to switch to normal, scientific, engineering,
+or fix display format, respectively, and @samp{D}, @samp{R}, @samp{F},
+and @samp{S} to turn on degrees, radians, fraction and symbolic modes,
+respectively. In addition, you may provide a @code{printf} format
+specifier to reformat the final result. A few examples:
+@example
+ $1+$2 @r{Sum of first and second field}
+ $1+$2;%.2f @r{Same, format result to two decimals}
+ exp($2)+exp($1) @r{Math functions can be used}
+ $;%.1f @r{Reformat current cell to 1 decimal}
+ ($3-32)*5/9 @r{Degrees F -> C conversion}
+ $c/$1/$cm @r{Hz -> cm conversion, using @file{constants.el}}
+ tan($1);Dp3s1 @r{Compute in degrees, precision 3, display SCI 1}
+ sin($1);Dp3%.1e @r{Same, but use printf specifier for display}
+ vmean($2..$7) @r{Compute column range mean, using vector function}
+ vsum(&III) @r{Sum numbers from 3rd hline above to here}
+ taylor($3,x=7,2) @r{taylor series of $3, at x=7, second degree}
+@end example
+
+@node Column formulas, Advanced features, Formula syntax, Table calculations
+@subsection Column formulas
+
+To apply a formula to a field, type it directly into the field,
+preceded by an equal sign, like @samp{=$1+$2}. When you press
+@key{TAB} or @key{RET} or @kbd{C-c C-c} with the cursor still in the
+field, the formula will be stored as the formula for the current
+column, evaluated and the current field replaced with the result. If
+the field contains only @samp{=}, the previously stored formula for
+this column is used.
+
+For each column, Org-mode will remember the most recently used
+formula. The information is stored in a special line starting with
+@samp{#+TBLFM} directly below the table. When adding/deleting/moving
+columns with the appropriate commands, the stored equations will be
+modified accordingly. When a column used in a calculation is removed,
+references to this column become invalid and will cause an error upon
+applying the equation.
+
+Instead of typing an equation into the field, you may also use the
+command @kbd{C-c =}. It prompts for a formula (with default taken
+from the @samp{#+TBLFM:} line) and applies it to the current field. A
+numerical prefix (e.g. @kbd{C-5 C-c =}) will apply it to that many
+subsequent fields in the current column.
+
+To recompute all the fields in a line, use the command @kbd{C-c *}.
+It re-applies all stored equations to the current row, from left to
+right. With a @kbd{C-u} prefix, this will be done to every line in
+the table, so use this command it you want to make sure the entire
+table is up-to-date. @kbd{C-u C-c C-c} is another way to update the
+entire table. Global updating does not touch the line(s) above the
+first horizontal separator line, assuming that this is the table
+header.
+
+@node Advanced features, Named-field formulas, Column formulas, Table calculations
+@subsection Advanced features
+
+If you want want the recalculation of fields to happen automatically,
+or if you want to be able to assign a formula to an individual field
+(instead of an entire column) you need to reserve the first column of
+the table for special marking characters. Here is an example of a
+table that collects exam results of students and makes use of these
+features:
+@example
+@group
+|---+---------+--------+--------+--------+-------+------|
+| | Student | Prob 1 | Prob 2 | Prob 3 | Total | Note |
+|---+---------+--------+--------+--------+-------+------|
+| ! | | P1 | P2 | P3 | Tot | |
+| # | Maximum | 10 | 15 | 25 | 50 | 10.0 |
+| ^ | | m1 | m2 | m3 | mt | |
+|---+---------+--------+--------+--------+-------+------|
+| # | Peter | 10 | 8 | 23 | 41 | 8.2 |
+| # | Sara | 6 | 14 | 19 | 39 | 7.8 |
+| # | Sam | 2 | 4 | 3 | 9 | 1.8 |
+|---+---------+--------+--------+--------+-------+------|
+| | Average | | | | 29.7 | |
+| ^ | | | | | at | |
+| $ | max=50 | | | | | |
+|---+---------+--------+--------+--------+-------+------|
+#+TBLFM: $6=vsum($P1..$P3)::$7=10*$Tot/$max;%.1f::$at=vmean(&II);%.1f
+@end group
+@end example
+
+@noindent @b{Important}: Please note that for these special tables,
+recalculating the table with @kbd{C-u C-c *} does only affect rows
+which are marked @samp{#} or @samp{*}, and named fields. The column
+formulas are not applied in rows with empty first field.
+
+The marking characters have the following meaning:
+@table @samp
+@item !
+The fields in this line define names for the columns, so that you may
+refer to a column as @samp{$Tot} instead of @samp{$6}.
+@item ^
+This row define names for the fields @emph{above} the row. With such
+a definition, any formula in the table may use @samp{$m1} to refer to
+the value @samp{10}. Also, named fields can have their own formula
+associated with them.
+@item _
+Similar to @samp{^}, but defines names for the fields in the row
+@emph{below}.
+@item $
+Fields in this row can define @emph{parameters} for formulas. For
+example, if a field in a @samp{$} row contains @samp{max=50}, then
+formulas in this table can refer to the value 50 using @samp{$max}.
+Parameters work exactly like constants, only that they can be defined on
+a per-table basis. Changing a parameter and then recalculating the
+table can be useful.
+@item #
+Fields in this row are automatically recalculated when pressing
+@key{TAB} or @key{RET} or @kbd{S-@key{TAB}} in this row. Also, this row
+is selected for a global recalculation with @kbd{C-u C-c *}. Unmarked
+lines will be left alone by this command.
+@item *
+Selects this line for global recalculation with @kbd{C-u C-c *}, but
+not for automatic recalculation. Use this when automatic
+recalculation slows down editing too much.
+@item
+Unmarked lines are exempted from recalculation with @kbd{C-u C-c *}.
+All lines that should be recalculated should be marked with @samp{#}
+or @samp{*}.
+@end table
+
+@node Named-field formulas, Editing/debugging formulas, Advanced features, Table calculations
+@subsection Named-field formulas
+
+A named field can have its own formula associated with it. In the
+example above, this is used for the @samp{at} field that contains
+the average result of the students. To enter a formula for a named
+field, just type it onto the buffer, preceded by @samp{:=}. Or use
+@kbd{C-u C-c =}. This equation will be stored below the table like
+@samp{$name=...}. Any recalculation in the table (even if only
+requested for the current line) will also update all named field
+formulas.
+
+@node Editing/debugging formulas, Appetizer, Named-field formulas, Table calculations
+@subsection Editing and debugging formulas
+
+To edit a column or field formula, you can use the commands @kbd{C-c
+=} and @kbd{C-u C-c =}, respectively. The currently active expression
+is then presented as default in the minibuffer, were it may be edited.
+
+Note that making a table field blank does not remove the formula
+associated with the field - during the next recalculation the field
+will be filled again. To remove a formula from a field, you have to
+give an empty reply when prompted for the formula, or to edit the
+@samp{#+TBLFM} line.
+
+@kindex C-c C-c
+You may edit the @samp{#+TBLFM} directly and re-apply
+the changed equations with @kbd{C-c C-c} in that line, or with the
+normal recalculation commands in the table.
+
+@kindex C-c '
+@kindex C-c C-c
+@kindex C-c C-q
+@kindex C-c ?
+In particular for large tables with many formulas, it is convenient to
+use the command @kbd{C-c '} to edit the formulas of the current table

+@subsection Time-of-Day Specifications
+
+Org-mode checks each agenda item for a time-of-day specification. The
+time can be part of the time stamp that triggered inclusion into the
+agenda, for example as in @w{@samp{<2005-05-10 Tue 19:00>}}. Time
+ranges can be specified with two time stamps, like
+@c
+@w{@samp{<2005-05-10 Tue 20:30>--<2005-05-10 Tue 22:15>}}.
+
+In the headline of the entry itself, a time(range) may also appear as
+plain text (like @samp{12:45} or a @samp{8:30-1pm}. If the agenda
+integrates the Emacs diary (@pxref{Calendar/Diary integration}), time
+specifications in diary entries are recognized as well.
+
+For agenda display, Org-mode extracts the time and displays it in a
+standard 24 hour format as part of the prefix. The example times in
+the previous paragraphs would end up in the agenda like this:
+
+@example
+ 8:30-13:00 Arthur Dent lies in front of the bulldozer
+ 12:45...... Ford Prefect arrives and takes Arthur to the pub
+ 19:00...... The Vogon reads his poem
+ 20:30-22:15 Marwin escorts the Hitchhikers to the bridge
+@end example
+
+If the agenda is in single-day mode, or for the display of today, the
+timed entries are embedded in a time grid, like
+
+@example
+ 8:00...... ------------------
+ 8:30-13:00 Arthur Dent lies in front of the bulldozer
+ 10:00...... ------------------
+ 12:00...... ------------------
+ 12:45...... Ford Prefect arrives and takes Arthur to the pub
+ 14:00...... ------------------
+ 16:00...... ------------------
+ 18:00...... ------------------
+ 19:00...... The Vogon reads his poem
+ 20:00...... ------------------
+ 20:30-22:15 Marwin escorts the Hitchhikers to the bridge
+@end example
+
+The time grid can be turned on and off with the variable
+@code{org-agenda-use-time-grid}, and can be configured with

@cindex indirect buffers
-@item
-It can be useful to have two different windows showing the same
-Org-mode file. However, a problem here is that changes to the
-visibility in one window immediately affect the other window. On
-Emacs (not on XEmacs because it uses the old outline-mode) a way out
-is the use of @emph{indirect buffers}, which visit the same file, but
-have separate settings, also for outline visibility. See the
-documentation on the command @code{make-indirect-buffer}.
+In GNU Emacs, you may use @emph{indirect buffers} which do exactly
+this. See the documentation on the command
+@code{make-indirect-buffer}. In XEmacs, this is currently not
+possible because of the different outline implementation.
+@item @b{Is there an easy way to insert links to web locations?}@*
@cindex URL, paste into buffer
-@item
-Paste URLs into Org-mode whenever this seems useful. For example, if
-you are writing notes about a paper which is available on the web, put
-the corresponding URL there and a direct look at the paper is only a
-mouse click away. If you have a local copy of the paper, use a
-file:path link.
+Sure, just type or paste them into the buffer. A plain-text URL-like
+string is directly interpreted as a link.
-@cindex headline levels, for export
-@item
+@item @b{When I export my TODO list, every TODO item becomes a
+separate section. How do I enforce these items to be exported as an
+itemized list?}@*
If you plan to use ASCII or HTML export, make sure things you want to
be exported as item lists are level 4 at least, even if that does mean
there is a level jump. For example
+OPTIONS: H:2; ...
@end example
+@item @b{I would like to export only a subtree of my file to HTML. How?}@*
@cindex exporting a subtree
-@item
If you want to export a subtree, mark the subtree as region and then
export. Marking can be done with @kbd{C-c @@ C-x C-x}, for example.
+@item @b{Org-mode takes over the S-cursor keys. I also want to use
+CUA-mode, is there a way to fix this conflict?}@*
+Yes, see @ref{Interaction}
+
+@item @b{Is there an easy way to insert an empty table template with a
+default number of rows and columns?}@*
@cindex table, empty template
-@item
To insert an empty table template, just type @samp{|-} and use
-@key{TAB}.
-
-@item
-In a table, to add a new column at the end, just type some text
-anywhere after the final @samp{|}. Upon the next re-align, a new
-column will be created.
-
-@item
-In tables, @key{TAB} creates new rows before horizontal separator lines. If
-the cursor is at @samp{Age} in the following table,
-
-@example
-| Name | Phone | Age |
-|-------+-------+-----|
-| | | |
-@end example
-
-the next @key{TAB} would create a second header line. If you want
-instead to go to the first empty field below the horizontal line,
-press @key{down} (to get on the separator line) and then @key{TAB}.
-
+@key{TAB}. The default size can be changed with the variable
+@code{org-table-default-size}. However, just starting to type the
+first line is usually much easier.
+
+@item @b{One of my table columns has started to fill up with
+@samp{#ERROR}. What is going on?}@*
+Org-mode tried to compute the column from other fields using a
+formula stored in the @samp{#+TBLFMT:} line just below the table, and
+the evaluation of the formula fails. Fix the fields used in the
+formula, or fix the formula, or remove it!
+
+@item @b{When I am in the last column of a table and just above a
+horizontal line in the table, pressing TAB creates a new table line
+@i{before} the horizontal line. How can I quickly move to the line
+@i{below} the horizontal line instead?}@*
+Press @key{down} (to get on the separator line) and then @key{TAB}.
+
+@item @b{How can I change the indentation of an entire table without
+fixing every line by hand?}@*
@cindex indentation, of tables
-@item
-To change the indentation of a table, just change the first line and
-realign with @key{TAB}.
+The indentation of a table is set by the first line. So just fix the
+indentation of the first line and realign with @key{TAB}.

-@cindex @file{planner.el}

+Org-mode can cooperate with the following packages:
@table @asis
+@cindex @file{table.el}
+@item @file{table.el} by Takaaki Ota
+Org mode cooperates with table.el, see @ref{table.el}.
+@cindex @file{calc.el}
+@item @file{calc.el} by Dave Gillespie
+Org-mode uses the calc package for implementing spreadsheet
+functionality in its tables (@pxref{Table calculations}). Org-modes
+checks for the availability of calc by looking for the function
+@code{calc-eval} which should be autoloaded in your setup if calc has
+been installed properly. As of Emacs 22, calc is part of the Emacs
+distribution. Another possibility for interaction between the two
+packages is using calc for embedded calculations. @xref{Embedded Mode,
+, Embedded Mode, calc, GNU Emacs Calc Manual}.
+@cindex @file{constants.el}
+@item @file{constants.el} by Carsten Dominik
+In a table formula (@pxref{Table calculations}), it is possible to use
+names for natural constants or units. Instead of defining you own
+constants in the variable @code{org-table-formula-constants}, install
+the @file{constants} package which defines a large number of constants
+and units, and lets you use unit prefixes like @samp{M} for
+@samp{Mega} etc. You will need version 2.0 of this package, available
+at @url{http://www.astro.uva.nl/~dominik/Tools}. Org-mode checks for
+the function @code{constants-get}, which has to be autoloaded in your
+setup. See the installation instructions in the file
+@file{constants.el}.
@cindex @file{remember.el}
+@cindex @file{CUA.el}
+@item @file{CUA.el} by Kim. F. Storm
+Keybindings in Org-mode conflict with the @kbd{S-<cursor>} keys
+used by CUA-mode (as well as pc-select-mode and s-region-mode) to
+select and extend the region. If you want to use one of these
+packages along with Org-mode, configure the variable
+@code{org-CUA-compatible}. When set, Org-mode will move the following
+keybindings in org-mode files, and in the agenda buffer (but not
+during date selection).
+@example
+S-UP -> M-p S-DOWN -> M-n
+S-LEFT -> M-- S-RIGHT -> M-+
+S-RET -> C-S-RET
+@end example
+Yes, these are unfortunately more difficult to remember. If you want
+to have other replacement keys, look at the variable
+@code{org-disputed-keys}.
@item @file{remember.el} by John Wiegley
Org mode cooperates with remember, see @ref{Remember}.

Planner is another tool to plan work and keep track of tasks. Planner
uses a multi-file approach with project pages and day pages. Is based
-on Emacs-Wiki. It can be useful to display the agenda entries
-resulting from org files in day-pages of the planner. This can be
-done through the diary of the calendar: Integrate org files into the
-diary as described above, and then turn on the diary support of

+Here is a list of things which should work differently, but which I
+have found too hard to fix.
+
+@itemize @bullet
+@item
+If you call @code{fill-paragraph} (bound to @kbd{M-q}) in a table, the
+filling is correctly disabled. However, if some text directly
+(without an empty line in between) precedes or follows a table, calling
+@code{fill-paragraph} in that text will also fill the table like
+normal text. Also, @code{fill-region} does bypass the
+@code{fill-paragraph} code and will fill tables like normal text.
+@item
+When the application called by @kbd{C-c C-o} to open a file link fails
+(for example because the application does not exits or refuses to open
+the file), it does so silently. No error message is displayed.
+@item
+Recalculating a table line applies the formulas from left to right.
+If a formula calculated fields further down the row, multiple
+recalculation may be needed to get all fields consistent.
+@item
+Under XEmacs, if Org-mode entries are included into the diary, it is
+not possible to jump back from the diary to the org file. Apparently,
+the text properties are lost when the fancy-diary-display is used.
+However, from Org-mode's timeline and agenda buffers (created with
+@kbd{C-c C-r} and @kbd{C-c a}), things do work correctly.
+@item
+Linux should also have a default viewer application, using mailcap.
+Maybe we can use GNUS or VM mime code? Or dired's guessing commands?
+Any hints (or even patches) are appreciated.
+@item
+When you write @samp{x = a /b/ c}, b will be exported in italics.
+@item
+The exporters work well, but could be made more efficient.
