+API DOCUMENTATION
   General API Considerations
     All objects (such as terminals, time watchers etc.) are typical
     reference-to-hash objects. The hash can be used to store anything you
     like. All members starting with an underscore (such as "_ptr" or
     "_hook") are reserved for internal uses and MUST NOT be accessed or
     $octets
         Either binary data or - more common - a text string encoded in a
         locale-specific way.
+  Extension Objects
+    Very perl extension is a perl class. A separate perl object is created
+    for each terminal and each extension and passed as the first parameter
+    to hooks. So extensions can use their $self object without having to
+    think about other extensions, with the exception of methods and members
+    that begin with an underscore character "_": these are reserved for
+    internal use.
+    Although it isn't a "urxvt::term" object, you can call all methods of
+    the "urxvt::term" class on this object.
+    It has the following methods and data members:
+    $urxvt_term = $self->{term}
+        Returns the "urxvt::term" object associated with this instance of
+        the extension. This member *must not* be changed in any way.
+    $self->enable ($hook_name => $cb, [$hook_name => $cb..])
+        Dynamically enable the given hooks (named without the "on_" prefix)
+        for this extension, replacing any previous hook. This is useful when
+        you want to overwrite time-critical hooks only temporarily.
+    $self->disable ($hook_name[, $hook_name..])
+        Dynamically disable the given hooks.
   Hooks
     The following subroutines can be declared in extension files, and will
     be called whenever the relevant event happens.
-    The first argument passed to them is an object private to each terminal
+    The first argument passed to them is an extension oject as described in
-    and extension package. You can call all "urxvt::term" methods on it, but
+    the in the "Extension Objects" section.
-    its not a real "urxvt::term" object. Instead, the real "urxvt::term"
-    object that is shared between all packages is stored in the "term"
-    member. It is, however, blessed intot he package of the extension
-    script, so for all practical purposes you can treat an extension script
-    as a class.
-    All of them must return a boolean value. If it is true, then the event

+    *When in doubt, return a false value (preferably "()").*
     on_init $term
         Called after a new terminal object has been initialized, but before
         windows are created or the command gets run. Most methods are unsafe
         to call or deliver senseless data, as terminal size and other
         may be larger than the scroll back buffer or the terminal.
         It is called before lines are scrolled out (so rows 0 .. min ($lines
         - 1, $nrow - 1) represent the lines to be scrolled out). $saved is
         the total number of lines that will be in the scrollback buffer.
-    on_tty_activity $term *NYI*
-        Called whenever the program(s) running in the urxvt window send
-        output.
     on_osc_seq $term, $string
         Called whenever the ESC ] 777 ; string ST command sequence (OSC =
         operating system command) is processed. Cursor position and other
         state information is up-to-date when this happens. For
         argument. You can filter/change and output the text yourself by
         returning a true value and calling "$term->scr_add_lines" yourself.
         Please note that this might be very slow, however, as your hook is
         called for all text being output.
+    on_tt_write $term, $octets
+        Called whenever some data is written to the tty/pty and can be used
+        to suppress or filter tty input.
     on_line_update $term, $row
         Called whenever a line was updated or changed. Can be used to filter
         screen output (e.g. underline urls or other useless stuff). Only
         lines that are being shown will be filtered, and, due to performance
         reasons, not always immediately.
     on_focus_out $term
         Called wheneever the window loses keyboard focus, before
         rxvt-unicode does focus out processing.

   Variables in the "urxvt" Package
+    $urxvt::LIBDIR
+        The rxvt-unicode library directory, where, among other things, the
+        perl modules and scripts are stored.

+    $urxvt::RXVTNAME
+        The basename of the installed binaries, usually "urxvt".
     $urxvt::TERM

   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
         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.
+    $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.
     $time = urxvt::NOW
         Returns the "current time" (as per the event loop).
     urxvt::CurrentTime
     urxvt::ShiftMask, LockMask, ControlMask, Mod1Mask, Mod2Mask, Mod3Mask,
     $foreground = urxvt::GET_BASEFG $rend
     $background = urxvt::GET_BASEBG $rend
         Return the foreground/background colour index, respectively.

-    $rend = urxvt::SET_BGCOLOR ($rend, $new_colour)
+    $rend = urxvt::SET_BGCOLOR $rend, $new_colour
         Replace the foreground/background colour in the rendition mask with
         the specified one.
-    $value = urxvt::GET_CUSTOM ($rend)
+    $value = urxvt::GET_CUSTOM $rend
         Return the "custom" value: Every rendition has 5 bits for use by
         extensions. They can be set and changed as you like and are
         initially zero.
-    $rend = urxvt::SET_CUSTOM ($rend, $new_value)
+    $rend = urxvt::SET_CUSTOM $rend, $new_value
         Change the custom value.
   The "urxvt::anyevent" Class
     The sole purpose of this class is to deliver an interface to the
     "AnyEvent" module - any module using it will work inside urxvt without
-    further work. The only exception is that you cannot wait on condition
+    further programming. The only exception is that you cannot wait on
-    variables, but non-blocking condvar use is ok. What this means is that
+    condition variables, but non-blocking condvar use is ok. What this means
-    you cannot use blocking APIs, but the non-blocking variant should work.
+    is that you cannot use blocking APIs, but the non-blocking variant
+    should work.
   The "urxvt::term" Class
     $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.
     $isset = $term->option ($optval[, $set])
         Returns true if the option specified by $optval is enabled, and
         optionally change it. All option values are stored by name in the
         hash %urxvt::OPTION. Options not enabled in this binary are not in

     $rend = $term->rstyle ([$new_rstyle])
         Return and optionally change the current rendition. Text that is
         output by the terminal application will use this style.
     ($row, $col) = $term->screen_cur ([$row, $col])
     $oldtext = $term->selection ([$newtext])

         Create a new (empty) overlay at the given position with the given
         width/height. $rstyle defines the initial rendition style (default:
         "OVERLAY_RSTYLE").
         Convert the given text string into the corresponding locale
         encoding.

+    $term->scr_xor_span ($beg_row, $beg_col, $end_row, $end_col[, $rstyle])
+        XORs the rendition values in the given span with the provided value
+        (default: "RS_RVid"). Useful in refresh hooks to provide effects
+        similar to the selection.
+    $term->scr_xor_rect ($beg_row, $beg_col, $end_row, $end_col[, $rstyle1[,
+    $rstyle2]])
+        Similar to "scr_xor_span", but xors a rectangle instead. Trailing
+        whitespace will additionally be xored with the $rstyle2, which
+        defaults to "RS_RVid | RS_Uline", which removes reverse video again
+        and underlines it instead.
+    $term->scr_bell
+        Ring the bell!
     $term->scr_add_lines ($string)
         Write the given text string to the screen, as if output by the
         application running inside the terminal. It may not contain command
         sequences (escape codes), but is free to use line feeds, carriage
     $term->tt_write ($octets)
         Write the octets given in $data to the tty (i.e. as program input).
         To pass characters instead of octets, you should convert your
         strings first to the locale-specific encoding using
         "$term->locale_encode".
+    $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.
     $windowid = $term->parent
         Return the window id of the toplevel window.
     $windowid = $term->vt
     $max_scrollback = $term->saveLines
     $nrow_plus_saveLines = $term->total_rows
     $lines_in_scrollback = $term->nsaved
         Return various integers describing terminal characteristics.
+    $lc_ctype = $term->locale
+        Returns the LC_CTYPE category string used by this rxvt-unicode.
+    $x_display = $term->display_id
+        Return the DISPLAY used by rxvt-unicode.
     $modifiermask = $term->ModLevel3Mask
     $modifiermask = $term->ModMetaMask
     $modifiermask = $term->ModNumLockMask
         Return the modifier masks corresponding to the "ISO Level 3 Shift"
         (often AltGr), the meta key (often Alt) and the num lock key, if
             the logical line.
         ($row, $col) = $line->coord_of ($offset)
             Translates a string offset into terminal coordinates again.
-    ($row, $col) = $line->coord_of ($offset) =item $text =
-    $term->special_encode $string
+    $text = $term->special_encode $string
         Converts a perl string into the special encoding used by
         rxvt-unicode, where one character corresponds to one screen cell.
         See "$term->ROW_t" for details.
     $string = $term->special_decode $text
         Converts rxvt-unicodes text reprsentation into a perl string. See
         "$term->ROW_t" for details.
+    $success = $term->grab_button ($button, $modifiermask)
+        Registers a synchronous button grab. See the XGrabButton manpage.
+    $success = $term->grab ($eventtime[, $sync])
+        Calls XGrabPointer and XGrabKeyboard in asynchronous (default) or
+        synchronous ($sync is true). Also remembers the grab timestampe.
+    $term->allow_events_async
+        Calls XAllowEvents with AsyncBoth for the most recent grab.
+    $term->allow_events_sync
+        Calls XAllowEvents with SyncBoth for the most recent grab.
+    $term->allow_events_replay
+        Calls XAllowEvents with both ReplayPointer and ReplayKeyboard for
+        the most recent grab.
+    $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.
   The "urxvt::popup" Class
+    $popup->add_title ($title)
+        Adds a non-clickable title to the popup.
+    $popup->add_separator ([$sepchr])
+        Creates a separator, optionally using the character given as
+        $sepchr.
+    $popup->add_button ($text, $cb)
+        Adds a clickable button to the popup. $cb is called whenever it is
+        selected.
+    $popup->add_toggle ($text, $cb, $initial_value)

+        whenever it gets toggled, with a boolean indicating its value as its
+        first argument.
+    $popup->show
+        Displays the popup (which is initially hidden).
   The "urxvt::timer" Class
         This class implements timer watchers/events. Time is represented as
         a fractional number of seconds since the epoch. Example:
            $term->{overlay} = $term->overlay (-1, 0, 8, 1, urxvt::OVERLAY_RSTYLE, 0);
           $term->{socket} = ...
