-=item selection
+=item selection (enabled by default)
 Intelligent selection. This extension tries to be more intelligent when
 the user extends selections (double-click). Right now, it tries to select
 urls and complete shell-quoted arguments, which is very convenient, too,
 if your F<ls> supports C<--quoting-style=shell>.

+Binds a popup menu to Ctrl-Button3 that lets you convert the selection
+text into various other formats/action.
 =item digital-clock
 Displays a digital clock using the built-in overlay.
+=item mark-urls
+Uses per-line display filtering (C<on_line_update>) to underline urls.
+=item 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.
 =item example-refresh-hooks
 Displays a very simple digital clock in the upper right corner of the
 window. Illustrates overwriting the refresh callbacks to create your own
 overlays or changes.

+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
 counts as being I<consumed>, and the invocation of other hooks is skipped,
 and the relevant action might not be carried out by the C++ code.

+windows are created or the command gets run. Most methods are unsafe to

 than the scroll back buffer or the terminal.
 It is called before lines are scrolled out (so rows 0 .. min ($lines - 1,
 $nrow - 1) represent the lines to be scrolled out). C<$saved> is the total
 number of lines that will be in the scrollback buffer.
-=item on_tty_activity $term *NYI*
-Called whenever the program(s) running in the urxvt window send output.
 =item on_osc_seq $term, $string
 Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
 operating system command) is processed. Cursor position and other state
 can filter/change and output the text yourself by returning a true value
 and calling C<< $term->scr_add_lines >> yourself. Please note that this
 might be very slow, however, as your hook is called for B<all> text being
 output.
+=item 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.
+The row number is always the topmost row of the line if the line spans
+multiple rows.
+Please note that, if you change the line, then the hook might get called
+later with the already-modified line (e.g. if unrelated parts change), so
+you cannot just toggle rendition bits, but only set them.
 =item on_refresh_begin $term
 Called just before the screen gets redrawn. Can be used for overlay
 or similar effects by modify terminal contents in refresh_begin, and
 restoring them in refresh_end. The built-in overlay and selection display
 Called whenever the user presses a key combination that has a
 C<perl:string> action bound to it (see description of the B<keysym>

 =over 4
+=item $term = new urxvt [arg...]
+Creates a new terminal, very similar as if you had started it with
+C<system $binfile, arg...>. Croaks (and probably outputs an error message)
+if the new instance couldn't be created.  Returns C<undef> if the new
+instance didn't initialise perl, and the terminal object otherwise. The
+C<init> and C<start> hooks will be called during the call.
 =item 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
 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.
+=item $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.
 =item $time = urxvt::NOW
 Returns the "current time" (as per the event loop).

 =item $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
 C<< $term->ROW_t >> for details.
 =item $string = $term->special_decode $text
 Converts rxvt-unicodes text reprsentation into a perl string. See
 C<< $term->ROW_t >> for details.
+=item $success = $term->grab_button ($button, $modifiermask)
+Registers a synchronous button grab. See the XGrabButton manpage.
+=item $success = $term->grab ($eventtime[, $sync])
+Calls XGrabPointer and XGrabKeyboard in asynchronous (default) or
+synchronous (C<$sync> is true). Also remembers the grab timestampe.
+=item $term->allow_events_async
+Calls XAllowEvents with AsyncBoth for the most recent grab.
+=item $term->allow_events_sync
+Calls XAllowEvents with SyncBoth for the most recent grab.
+=item $term->allow_events_replay
+Calls XAllowEvents with both ReplayPointer and ReplayKeyboard for the most
+recent grab.
+=item $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.

 =head2 The C<urxvt::timer> Class
 This class implements timer watchers/events. Time is represented as a
 fractional number of seconds since the epoch. Example:
 This variable controls the verbosity level of the perl extension. Higher
 numbers indicate more verbose output.
