77
78Adds regex search functionality to the scrollback buffer, triggered

81screen.

86bottom. C<Escape> leaves search mode and returns to the point where search
87was started, while C<Enter> or C<Return> stay at the current position and

154=head2 Extension Objects
155
156Very perl extension is a perl class. A separate perl object is created
157for each terminal and each extension and passed as the first parameter to
158hooks. So extensions can use their C<$self> object without having to think
159about other extensions, with the exception of methods and members that
160begin with an underscore character C<_>: these are reserved for internal
161use.
162
163Although it isn't a C<urxvt::term> object, you can call all methods of the
164C<urxvt::term> class on this object.
165
166It has the following methods and data members:

173extension. This member I<must not> be changed in any way.
174
175=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
176
177Dynamically enable the given hooks (named without the C<on_> prefix) for
178this extension, replacing any previous hook. This is useful when you want
179to overwrite time-critical hooks only temporarily.
