     selection (enabled by default)
         (More) intelligent selection. This extension tries to be more
-        intelligent when the user extends selections (double-click). Right

+        complete shell-quoted arguments, which is very convenient, too, if
-        "--quoting-style=shell".
+        your ls supports "--quoting-style=shell".
+        A double-click usually selects the word under the cursor, further
+        clicks will enlarge the selection.
+        The selection works by trying to match a number of regexes and
+        displaying them in increasing order of length. You can add your own
+        regexes by specifying resources of the form:
+           URxvt.selection.pattern-0: perl-regex
+           URxvt.selection.pattern-1: perl-regex
+           ...
+        The index number (0, 1...) must not have any holes, and each regex
+        must contain at least one pair of capturing parentheses, which will
+        be used for the match. For example, the followign adds a regex that
+        matches everything between two vertical bars:
+           URxvt.selection.pattern-0: \\|([^|]+)\\|
+        You can look at the source of the selection extension to see more
+        interesting uses, such as parsing a line from beginning to end.

         unescaping, perl evalution, web-browser starting etc.), depending on
         content.

-    digital-clock
+    selection-autotransform
-        Displays a digital clock using the built-in overlay.
+        This selection allows you to do automatic transforms on a selection
+        whenever a selection is made.
+        It works by specifying perl snippets (most useful is a single "s///"
+        operator) that modify $_ as resources:
+           URxvt.selection-autotransform.0: transform
+           URxvt.selection-autotransform.1: transform
+           ...
+        For example, the following will transform selections of the form
+        "filename:number", often seen in compiler messages, into "vi
+        +$filename $word":
+           URxvt.selection-autotransform.0: s/^(\\S+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
+        And this example matches the same,but replaces it with vi-commands
+        you can paste directly into your (vi :) editor:
+           URxvt.selection-autotransform.0: s/^(S+):(d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
+        Of course, this can be modified to suit your needs and your editor
+        :)
+        To expand the example above to typical perl error messages ("XXX at
+        FILENAME line YYY."), you need a slightly more elaborate solution:
+           URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
+           URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
+        The first line tells the selection code to treat the unchanging part
+        of every error message as a selection pattern, and the second line
+        transforms the message into vi commands to load the file.

+        and make them clickable. When middle-clicked, the program specified
+        in the resource "urlLauncher" (default "x-www-browser") will be
+        started with the URL as first argument.
     block-graphics-to-ascii
         A not very useful example of filtering all text output to the
         terminal, by replacing all line-drawing characters (U+2500 ..
         U+259F) by a similar-looking ascii character.

         your own overlays or changes.
     Argument names also often indicate the type of a parameter. Here are
     some hints on what they mean:

         unicode characters and is to be distinguished with text encoded in a
     on_sel_extend $term
         Called whenever the user tries to extend the selection (e.g. with a
         double click) and is either supposed to return false (normal
         operation), or should extend the selection itelf and return true to
-        suppress the built-in processing.
+        suppress the built-in processing. This can happen multiple times, as
+        long as the callback returns true, it will be called on every
+        further click by the user and is supposed to enlarge the selection
+        more and more, if possible.
         See the selection example extension.
     on_view_change $term, $offset
         Called whenever the view offset changes, i..e the user or program
     $urxvt::TERM
         The current terminal. This variable stores the current "urxvt::term"
         object, whenever a callback/hook is executing.

   Functions in the "urxvt" Package
-    $term = new urxvt [arg...]
-        Creates a new terminal, very similar as if you had started it with
-        "system $binfile, arg...". Croaks (and probably outputs an error
-        message) if the new instance couldn't be created. Returns "undef" if
-        the new instance didn't initialise perl, and the terminal object
-        otherwise. The "init" and "start" hooks will be called during the
-        call.
     urxvt::fatal $errormessage
         Fatally aborts execution with the given error message. Avoid at all
         costs! The only time this is acceptable is when the terminal process
         starts up.
         newline. The module also overwrites the "warn" builtin with a
         function that calls this function.
         Using this function has the advantage that its output ends up in the
         correct place, e.g. on stderr of the connecting urxvtc client.
+        Messages have a size limit of 1023 bytes currently.
     $is_safe = urxvt::safe
         Returns true when it is safe to do potentially unsafe things, such
         as evaluating perl code specified by the user. This is true when
         urxvt was started setuid or setgid.
     condition variables, but non-blocking condvar use is ok. What this means
     is that you cannot use blocking APIs, but the non-blocking variant
     should work.
   The "urxvt::term" Class
+    $term = new urxvt::term $envhashref, $rxvtname, [arg...]
+        Creates a new terminal, very similar as if you had started it with
+        system "$rxvtname, arg...". $envhashref must be a reference to a
+        %ENV-like hash which defines the environment of the new terminal.
+        Croaks (and probably outputs an error message) if the new instance
+        couldn't be created. Returns "undef" if the new instance didn't
+        initialise perl, and the terminal object otherwise. The "init" and
+        "start" hooks will be called during this call.
     $term->destroy
         Destroy the terminal object (close the window, free resources etc.).
         Please note that rxvt will not exit as long as any event watchers
         (timers, io watchers) are still active.

+        or class name, i.e. "$term->x_resource ("boldFont")" should return
+        the same value as used by this instance of rxvt-unicode. Returns
+        "undef" if no resource with that pattern exists.
+        This method should only be called during the "on_start" hook, as
+        there is only one resource database per display, and later
+        invocations might return the wrong resources.
     $success = $term->parse_keysym ($keysym_spec, $command_string)
         Adds a keymap translation exactly as specified via a resource. See
         the "keysym" resource in the rxvt(1) manpage.

+    $term->selection_make ($eventtime[, $rectangular])
