     can find them in /opt/rxvt/lib/urxvt/perl/.
     You can activate them like this:
       rxvt -pe <extensionname>
+    Or by adding them to the resource for extensions loaded by default:
+      URxvt.perl-ext-common: default,automove-background,selection-autotransform
     selection (enabled by default)
         (More) intelligent selection. This extension tries to be more
         intelligent when the user extends selections (double-click and
         further clicks). Right now, it tries to select words, urls and
         be used for the match. For example, the followign adds a regex that
         matches everything between two vertical bars:
            URxvt.selection.pattern-0: \\|([^|]+)\\|
+        Another example: Programs I use often output "absolute path: " at
+        the beginning of a line when they process multiple files. The
+        following pattern matches the filename (note, there is a single
+        space at the very end):
+           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.
         This extension also offers following bindable keyboard commands:
         options at runtime.
     selection-popup (enabled by default)
         Binds a popup menu to Ctrl-Button3 that lets you convert the
         selection text into various other formats/action (such as uri
-        unescaping, perl evalution, web-browser starting etc.), depending on
+        unescaping, perl evaluation, web-browser starting etc.), depending
-        content.
+        on content.
         Other extensions can extend this popup menu by pushing a code
         reference onto "@{ $term-"{selection_popup_hook} }>, that is called
         whenever the popup is displayed.
         "End" jumps to the bottom. "Escape" leaves search mode and returns
         to the point where search was started, while "Enter" or "Return"
         stay at the current position and additionally stores the first match
         in the current line into the primary selection.
+    readline (enabled by default)
+        A support package that tries to make editing with readline easier.
+        At the moment, it reacts to clicking with the left mouse button by
+        trying to move the text cursor to this position. It does so by
+        generating as many cursor-left or cursor-right keypresses as
+        required (the this only works for programs that correctly support
+        wide characters).
+        To avoid too many false positives, this is only done when:
+        - the tty is in ICANON state.
+        - the text cursor is visible.
+        - the primary screen is currently being displayed.
+        - the mouse is on the same (multi-row-) line as the text cursor.
+        The normal selection mechanism isn't disabled, so quick successive
+        clicks might interfere with selection creation in harmless ways.
     selection-autotransform
         This selection allows you to do automatic transforms on a selection
         whenever a selection is made.
         It works by specifying perl snippets (most useful is a single "s///"
            URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/: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.
+    tabbed
+        This transforms the terminal into a tabbar with additional
+        terminals, that is, it implements what is commonly refered to as
+        "tabbed terminal". The topmost line displays a "[NEW]" button,
+        which, when clicked, will add a new tab, followed by one button per
+        tab.
+        Clicking a button will activate that tab. Pressing Shift-Left and
+        Shift-Right will switch to the tab left or right of the current one,
+        while Shift-Down creates a new tab.
     mark-urls
         Uses per-line display filtering ("on_line_update") to underline urls
         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.
+    xim-onthespot
+        This (experimental) perl extension implements OnTheSpot editing. It
+        does not work perfectly, and some input methods don't seem to work
+        well with OnTheSpot editing in general, but it seems to work at
+        leats for SCIM and kinput2.
+        You enable it by specifying this extension and a preedit style of
+        "OnTheSpot", i.e.:
+           rxvt -pt OnTheSpot -pe xim-onthespot
     automove-background
         This is basically a one-line extension that dynamically changes the
         background pixmap offset to the window position, in effect creating
         the same effect as pseudo transparency with a custom pixmap. No
     be called whenever the relevant event happens.
     The first argument passed to them is an extension oject as described in
     the in the "Extension Objects" section.

     on_init $term
         Called after a new terminal object has been initialized, but before
         windows are created or the command gets run. Most methods are unsafe
         to call or deliver senseless data, as terminal size and other
         characteristics have not yet been determined. You can safely query
-        and change resources, though.
+        and change resources and options, though. For many purposes the
+        "on_start" hook is a better place.
+    on_start $term
+        Called at the very end of initialisation of a new terminal, just
+        before trying to map (display) the toplevel and returning to the
+        mainloop.
+    on_destroy $term
+        Called whenever something tries to destroy terminal, when the
+        terminal is still fully functional (not for long, though).
     on_reset $term
         Called after the screen is "reset" for any reason, such as resizing
         or control sequences. Here is where you can react on changes to
         size-related variables.
-    on_start $term
-        Called at the very end of initialisation of a new terminal, just
-        before returning to the mainloop.
     on_child_start $term, $pid
         Called just after the child process has been "fork"ed.
     on_child_exit $term, $status
     on_focus_out $term
         Called wheneever the window loses keyboard focus, before
         rxvt-unicode does focus out processing.

         terminal If the hook returns true, then the even will be ignored by
         rxvt-unicode.
         The event is a hash with most values as named by Xlib (see the
         XEvent manpage), with the additional members "row" and "col", which

+    on_client_message $term, $event
+    on_wm_protocols $term, $event
+    on_wm_delete_window $term, $event
+        Called when various types of ClientMessage events are received (all
+        with format=32, WM_PROTOCOLS or WM_PROTOCOLS:WM_DELETE_WINDOW).
   Variables in the "urxvt" Package
     $urxvt::LIBDIR
         The rxvt-unicode library directory, where, among other things, the
         perl modules and scripts are stored.
         The basename of the installed binaries, usually "urxvt".
     $urxvt::TERM
         The current terminal. This variable stores the current "urxvt::term"
         object, whenever a callback/hook is executing.
+    @urxvt::TERM_INIT
+        All coderefs in this array will be called as methods of the next
+        newly created "urxvt::term" object (during the "on_init" phase). The
+        array gets cleared before the codereferences that were in it are
+        being executed, so coderefs can push themselves onto it again if
+        they so desire.
+        This complements to the perl-eval commandline option, but gets
+        executed first.
+    @urxvt::TERM_EXT
+        Works similar to @TERM_INIT, but contains perl package/class names,
+        which get registered as normal extensions after calling the hooks in
+        @TERM_INIT but before other extensions. Gets cleared just like
+        @TERM_INIT.
   Functions in the "urxvt" Package
     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
         Normally its not a good idea to use this function, as programs might
         be confused by changes in cursor position or scrolling. Its useful
         inside a "on_add_lines" hook, though.
+    $term->scr_change_screen ($screen)
+        Switch to given screen - 0 primary, 1 secondary.
     $term->cmd_parse ($octets)
         Similar to "scr_add_lines", but the argument must be in the
         locale-specific encoding of the terminal and can contain command
         sequences (escape codes) that will be interpreted.
     $old_events = $term->pty_ev_events ([$new_events])
         Replaces the event mask of the pty watcher by the given event mask.
         Can be used to suppress input and output handling to the pty/tty.
         See the description of "urxvt::timer->events". Make sure to always
         restore the previous value.
+    $fd = $term->pty_fd
+        Returns the master file descriptor for the pty in use, or -1 if no
+        pty is used.
     $windowid = $term->parent
         Return the window id of the toplevel window.
     $windowid = $term->vt
     $modifiermask = $term->ModNumLockMask
         Return the modifier masks corresponding to the "ISO Level 3 Shift"
         (often AltGr), the meta key (often Alt) and the num lock key, if
         applicable.
+    $screen = $term->current_screen
+        Returns the currently displayed screen (0 primary, 1 secondary).
+    $cursor_is_hidden = $term->hidden_cursor
+        Returns wether the cursor is currently hidden or not.
     $view_start = $term->view_start ([$newvalue])
         Returns the row number of the topmost displayed line. Maximum value
         is 0, which displays the normal terminal contents. Lower values
         scroll this many lines into the scrollback buffer.
         line, starting at column $start_col (default 0), which is useful to
         replace only parts of a line. The font index in the rendition will
         automatically be updated.
         $text is in a special encoding: tabs and wide characters that use
-        more than one cell when displayed are padded with urxvt::NOCHAR
+        more than one cell when displayed are padded with $urxvt::NOCHAR
-        characters ("chr 65535"). Characters with combining characters and
+        (chr 65535) characters. Characters with combining characters and
         other characters that do not fit into the normal tetx encoding will
         be replaced with characters in the private use area.
         You have to obey this encoding when changing text. The advantage is
         that "substr" and similar functions work on screen cells and not on
     $term->ungrab
         Calls XUngrab for the most recent grab. Is called automatically on
         evaluation errors, as it is better to lose the grab in the error
         case as the session.
+    $atom = $term->XInternAtom ($atom_name[, $only_if_exists])
+    $atom_name = $term->XGetAtomName ($atom)

+    $term->XChangeInput ($window, $add_events[, $del_events])
+        Various X or X-related functions. The $term object only serves as
+        the source of the display, otherwise those functions map
+        more-or-less directory onto the X functions of the same name.
   The "urxvt::popup" Class
     $popup->add_title ($title)
         Adds a non-clickable title to the popup.
         Start watching for requested events on the given handle.
     $iow = $iow->stop
         Stop watching for events on the given filehandle.
+  The "urxvt::iw" Class
+    This class implements idle watchers, that get called automatically when
+    the process is idle. They should return as fast as possible, after doing
+    some useful work.
+    $iw = new urxvt::iw
+        Create a new idle watcher object in stopped state.
+    $iw = $iw->cb (sub { my ($iw) = @_; ... })
+        Set the callback to be called when the watcher triggers.
+    $timer = $timer->start
+        Start the watcher.
+    $timer = $timer->stop
+        Stop the watcher.
+  The "urxvt::pw" Class
+    This class implements process watchers. They create an event whenever a
+    process exits, after which they stop automatically.
+       my $pid = fork;
+       ...
+       $term->{pw} = urxvt::pw

+    $pw = $pw->cb (sub { my ($pw, $exit_status) = @_; ... })
+        Set the callback to be called when the timer triggers.
+    $pw = $timer->start ($pid)
+        Tells the wqtcher to start watching for process $pid.
+    $pw = $pw->stop
+        Stop the watcher.
