 =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 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

 =item 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

+=item 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.
+=item on_destroy $term
+Called whenever something tries to destroy terminal, before doing anything
+yet. If this hook returns true, then destruction is skipped, but this is
+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 on_child_start $term, $pid
 Called just after the child process has been C<fork>ed.
 Called wheneever the window loses keyboard focus, before rxvt-unicode does
 focus out processing.

 =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.

+Works similar to C<@TERM_INIT>, but contains perl package/class names, which
