+Every time a terminal object gets created, extension scripts specified via
 the C<perl> resource are loaded and associated with it.
 Scripts are compiled in a 'use strict' and 'use utf8' environment, and
 thus must be encoded as UTF-8.
 Each script will only ever be loaded once, even in @@RXVT_NAME@@d, where
 scripts will be shared (but not enabled) for all terminals.
+You can disable the embedded perl interpreter by setting both "perl-ext"
+and "perl-ext-common" resources to the empty string.

+=item kuake<hotkey>
+A very primitive quake-console-like extension. It was inspired by a
+description of how the programs C<kuake> and C<yakuake> work: Whenever the
+user presses a global accelerator key (by default C<F10>), the terminal
+will show or hide itself. Another press of the accelerator key will hide
+or show it again.
+Initially, the window will not be shown when using this extension.
+This is useful if you need a single terminal that is not using any desktop
+space most of the time but is quickly available at the press of a key.
+The accelerator key is grabbed regardless of any modifiers, so this
+extension will actually grab a physical key just for this function.

+We use it to implement a "distributed selection mechanism", which just
+means that one command uploads the file to a remote server, and another

+The commands can be set using the C<URxvt.remote-selection.store> and
+C<URxvt.remote-selection.fetch> resources. The first should read the
+selection to store from STDIN (always in UTF-8), the second should provide
+the selection data on STDOUT (also in UTF-8).

 The methods currently supported on C<urxvt::overlay> objects are:
 =over 4
-=item $overlay->set ($x, $y, $text, $rend)
+=item $overlay->set ($x, $y, $text[, $rend])
 Similar to C<< $term->ROW_t >> and C<< $term->ROW_r >> in that it puts
 text in rxvt-unicode's special encoding and an array of rendition values
 at a specific position inside the overlay.
+If C<$rend> is missing, then the rendition will not be changed.
 =item $overlay->hide
 If visible, hide the overlay, but do not destroy it.

 to receive pointer events all the times:

 automatically be updated.
