-Everytime a terminal object gets created, extension scripts specified via
+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.
 =head1 PREPACKAGED EXTENSIONS
 This section describes the extensions delivered with this release. You can
 find them in F<@@RXVT_LIBDIR@@/urxvt/perl/>.

 first argument.

 It should either return nothing or a string and a code reference. The
 string will be used as button text and the code reference will be called
 when the button gets activated and should transform C<$_>.
 The following will add an entry C<a to b> that transforms all C<a>s in
 the selection to C<b>s, but only if the selection currently contains any
 C<a>s:

+or simply use an uppercase character which removes the "(?i)" prefix.
+See L<perlre> for more info about perl regular expression syntax.
 =item readline (enabled by default)
 A support package that tries to make editing with readline easier. At
 the moment, it reacts to clicking shift-left mouse button by trying to
 the message into vi commands to load the file.

 displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
 button per tab.

 B<Shift-Right> will switch to the tab left or right of the current one,

+space most of the time but is quickly available at the press of a key.

 in the C<selection-pastebin-url> resource (again, the % is the placeholder
 for the filename):
