10    
11 sf-exg 1.30 Binds a popup menu to Ctrl-Button3 that lets you paste the X
12     selections and either modify or use the internal selection text in
13     various ways (such as uri unescaping, perl evaluation, web-browser
14     starting etc.), depending on content.
15 root 1.26
16     Other extensions can extend this popup menu by pushing a code reference
17 root 1.27 onto C<< @{ $term->{selection_popup_hook} } >>, which gets called whenever
18     the popup is being displayed.
19 root 1.26
20     Its sole argument is the popup menu, which can be modified. The selection
21     is in C<$_>, which can be used to decide whether to add something or not.
22     It should either return nothing or a string and a code reference. The
23     string will be used as button text and the code reference will be called
24     when the button gets activated and should transform C<$_>.
25    
26     The following will add an entry C<a to b> that transforms all C<a>s in
27     the selection to C<b>s, but only if the selection currently contains any
28     C<a>s:
29    
30     push @{ $self->{term}{selection_popup_hook} }, sub {
31     /a/ ? ("a to b" => sub { s/a/b/g }
32     : ()
33     };
