address@hidden properties
+
+Properties are a set of key-value pairs associated with an entry.  There
+are two main applications for properties in Org-mode.  First, properties
+are like tags, but with a value.  For example, in a file where you
+document bugs and plan releases of a piece of software, instead of using
+tags like @code{:release_1:}, @code{:release_2:}, it can be more
+efficient to use a property @code{RELEASE} with a value @code{1.0} or
address@hidden  Second, you can use properties to implement (very basic)
+database capabilities in an Org-mode buffer, for example to create a
+list of Music CD's you own.

address@hidden Property Syntax
+
+Properties are key-value pairs.  They need to be inserted into a special
+drawer (@pxref{Drawers}) with the name @code{PROPERTIES}.  Each property
+is specified on a single line, with the key (surrounded by colons)
+first, and the value after it.  Here is an example:

+TAGS         @r{The tags defined directly in the headline.}

address@hidden Property searches
+
+To create sparse trees and special lists with selection based on
+properties, the same commands are used as for tag searches (@pxref{Tag
+searches}), and the same logic applies.  For example, a search string
+
address@hidden
++WORK-BOSS+PRIORITY="A"+coffee="unlimited"address@hidden|address@hidden
address@hidden example
+
address@hidden
+finds entries tagged @samp{:WORK:} but not @samp{:BOSS:}, which
+also have a priority value @samp{A}, a @samp{:coffee:} property with the
+value @samp{unlimited}, and a @samp{:with:} property that is matched by
+the regular expression @samp{Sarah\|Denny}.

address@hidden Column view, Property API, Property searches, Properties
address@hidden Column View
+
+If different items in a document have similar properties, it can be nice
+to view and edit those properties in a table-like format, in
address@hidden view}.  Org-mode implements columns by overlaying a tabular
+structure over the headline of an item.  So the column view does not use
+a special buffer, it happens in exactly the same buffer where the
+outline is, and only temporarily changes the look of this buffer - not
+the content.  This has the advantage that you can still change the
+visibility of the outline tree.  For example, you get a compact table by
+switching to CONTENTS view, but you can still open, read, and edit the
+entry below each headline.  Or, you can switch to column view after
+executing a sparse tree command and in this way get a table only for the
+selected items.  Column view also works in agenda buffers (@pxref{Agenda
+views}) where queries have collected selected items, possibly from a
+number of files.

address@hidden menu
+
address@hidden Defining columns, Using column view, Column view, Column view
address@hidden Defining Columns
+
+Setting up a column view first requires defining the columns.  A column
+definition is a property itself and looks like this:
+
address@hidden
+:COLUMNS: %25ITEM %TAGS %PRIORITY %TODO
address@hidden example
+
+This definition means that column 1 should be the first 25 characters of
+the item itself, i.e. of the headline.  You probably always should start
+the column definition with the ITEM specifier - just select a useful
+width for it.  The other specifiers create columns for the local tags,
+for the priority and for the TODO state.  When no width is given after
+the @samp{%} character, the column will be exactly as wide as it need to
+be in order to fully display all values.
+
+If a @code{COLUMNS} property is present in an entry, it defines
+columns for the entry itself, and for the entire subtree below it.
+Since the column definition is part of the hierarchical structure of the
+document, you can define columns on level 1 that are general enough for
+all sublevels, and more specific columns further down, when you edit a deeper
+part of the tree.  Here is an example:
+
address@hidden
+* People
+  :PROPERTIES:
+  :COLUMNS: %25ITEM %Name
+  :END:
+** Family
+   :PROPERTIES:
+   :COLUMNS: %25ITEM %Name %3Age
+   :END:
+*** Sam
+    Info about Sam, including a property list with Name and Age.
+*** Sarah
+    Info about Sarah, including a property list with Name and Age.
+** Office
+   :PROPERTIES:
+   :COLUMNS: %25ITEM %Name %Function %Salary
+   :END:
+*** Boss
+    Info about the Boss, including a property list with Name,
+    Function and Salary (if only we knew....).
address@hidden example
+
+Now we have defined three different sets of columns.  If you switch to
+column view in the @emph{Family} section, you will get a different table
+than if you do it in the @emph{Office} section.  However, if you switch
+to column view with the cursor on the @emph{People} section, the table
+will cover all entries, but contain only the @emph{Name} column.
+
+If no COLUMNS property applies to a given location, Org-mode uses a
+default format specified in the variable
address@hidden  This format in particular also
+applies when column view is invoked with the cursor before the first
+headline.  You can set the default format on a per-file basis with a
+line (don't forget to press @kbd{C-c C-c} to activate any changes to
+this line).
+

+#+COLUMNS: %25ITEM ....."
