+=head1 NAME
+
+   selection-popup (enabled by default)
+
+=head1 DESCRIPTION
+
+Binds a popup menu to Ctrl-Button3 that lets you convert the selection
+text into various other formats/action (such as uri unescaping, perl
+evaluation, web-browser starting etc.), depending on content.
+
+Other extensions can extend this popup menu by pushing a code reference
+onto C<@{ $term->{selection_popup_hook} }>, which gets called whenever the
+popup is being displayed.
+
+Its sole argument is the popup menu, which can be modified. The selection
+is in C<$_>, which can be used to decide whether to add something or not.
+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:
+
+   push @{ $self->{term}{selection_popup_hook} }, sub {
+      /a/ ? ("a to b" => sub { s/a/b/g }
+          : ()
+   };
