     selection (enabled by default)
         (More) intelligent selection. This extension tries to be more

         It also offers the following bindable keyboard command:

             Rot-13 the selection when activated. Used via keyboard trigger:
         unescaping, perl evalution, web-browser starting etc.), depending on
         content.
     searchable-scrollback<hotkey> (enabled by default)

     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.
     Argument names also often indicate the type of a parameter. Here are
     some hints on what they mean:
     $text
         Rxvt-unicodes special way of encoding text, where one "unicode"
-        character always represents one screen cell. See row_t for a
+        character always represents one screen cell. See ROW_t for a
         discussion of this format.
     $string
         A perl text string, with an emphasis on *text*. It can store all
         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.

+    $value = $term->x_resource ($pattern)
+        Returns the X-Resource for the given pattern, excluding the program
+        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.

         Return the current values of the selection mark, begin or end
         positions, and optionally set them to new values.
+    $term->selection_make ($eventtime[, $rectangular])
+        Tries to make a selection as set by "selection_beg" and
+        "selection_end". If $rectangular is true (default: false), a
+        rectangular selection will be made. This is the prefered function to
+        make a selection.

+        hooks.
     $oldtext = $term->selection ([$newtext])
         Return the current selection text and optionally replace it by
         $newtext.
     $string = $term->locale_decode ($octets)
         Convert the given locale-encoded octets into a perl string.
     $term->scr_xor_span ($beg_row, $beg_col, $end_row, $end_col[, $rstyle])

         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

     $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

-        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"
             Return the row number of the first/last row of the line,
             respectively.
         $offset = $line->offset_of ($row, $col)

         ($row, $col) = $line->coord_of ($offset)
             Translates a string offset into terminal coordinates again.
