 =item 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 content.
+evaluation, web-browser starting etc.), depending on content.
 Other extensions can extend this popup menu by pushing a code reference
 onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
 popup is displayed.
 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.
+=item readline
+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).
+It only works when clicking into the same line (possibly extended over
+multiple rows) as the text cursor and on the primary screen, to reduce the
+risk of misinterpreting. The normal selection isn't disabled, so quick
+successive clicks might interfere with selection creation in harmless
+ways.
+=item 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 B<Shift-Left> and
+B<Shift-Right> will switch to the tab left or right of the current one,
+while B<Shift-Down> creates a new tab.
 =item mark-urls
 Uses per-line display filtering (C<on_line_update>) to underline urls and
 make them clickable. When middle-clicked, the program specified in the
 resource C<urlLauncher> (default C<x-www-browser>) will be started with
 called whenever the relevant event happens.
 The first argument passed to them is an extension oject as described in
 the in the C<Extension Objects> section.

+=item on_start $term
+Called at the very end of initialisation of a new terminal, just before

+Called whenever something tries to destroy terminal, before doing anything

+rarely a good idea.
 =item 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.

 =item $urxvt::LIBDIR
 =item $urxvt::TERM
 The current terminal. This variable stores the current C<urxvt::term>
 object, whenever a callback/hook is executing.
+=item @urxvt::TERM_INIT
+All coderefs in this array will be called as methods of the next newly
+created C<urxvt::term> object (during the C<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.
+=item @urxvt::TERM_EXT
+Works similar to C<@TERM_INIT>, but contains perl package/class names, which
+get registered as normal extensions after calling the hooks in C<@TERM_INIT>
+but before other extensions. Gets cleared just like C<@TERM_INIT>.

 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
 C<on_add_lines> hook, though.
+=item $term->scr_change_screen ($screen)
+Switch to given screen - 0 primary, 1 secondary.
 =item $term->cmd_parse ($octets)
 Similar to C<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.
 =item $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.
+=item $screen = $term->current_screen
+Returns the currently displayed screen (0 primary, 1 secondary).
 =item $view_start = $term->view_start ([$newvalue])
 Returns the row number of the topmost displayed line. Maximum value is
 C<0>, which displays the normal terminal contents. Lower values scroll
 this many lines into the scrollback buffer.
 If C<$new_text> is specified, it will replace characters in the current
 line, starting at column C<$start_col> (default C<0>), which is useful
 to replace only parts of a line. The font index in the rendition will
 automatically be updated.

 You have to obey this encoding when changing text. The advantage is
 that C<substr> and similar functions work on screen cells and not on
 characters.

 evaluation errors, as it is better to lose the grab in the error case as
 the session.
