+the user extends selections (double-click). Right now, it tries to select

 It also offers the following bindable event:

 =head2 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 C<_ptr> or
-C<_hook>) are reserved for internal uses and must not be accessed or
+C<_hook>) are reserved for internal uses and B<MUST NOT> be accessed or
 modified).
 When objects are destroyed on the C++ side, the perl object hashes are
 emptied, so its best to store related objects such as time watchers and
 the like inside the terminal object so they get destroyed as soon as the
 terminal is destroyed.
 =head2 Hooks

+The following subroutines can be declared in loaded scripts, and will be

+called whenever the relevant event happens.
+The first argument passed to them is an object private to each terminal
+and extension package.  You can call all C<urxvt::term> methods on it, but
+its not a real C<urxvt::term> object. Instead, the real C<urxvt::term>
+object that is shared between all packages is stored in the C<term>
+member.
 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.
 =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
+information is up-to-date when this happens. For interoperability, the
+string should start with the extension name and a colon, to distinguish
+it from commands for other extensions, and this might be enforced in the
+future.
+Be careful not ever to trust (in a security sense) the data you receive,
+as its source can not easily be controleld (e-mail content, messages from
+other users on the same system etc.).
 =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
 C<perl:string> action bound to it (see description of the B<keysym>
 resource in the @@RXVT_NAME@@(1) manpage).

 C<< $term->ROW_t >> for details.
 This variable controls the verbosity level of the perl extension. Higher
 numbers indicate more verbose output.
