selection-popup (enabled by default) |

=head1 DESCRIPTION |
| 10 |
|
| 11 |
Binds a popup menu to Ctrl-Button3 that lets you convert the selection |
| 12 |
text into various other formats/action (such as uri unescaping, perl |
| 13 |
evaluation, web-browser starting etc.), depending on content. |
| 14 |
|
| 15 |
Other extensions can extend this popup menu by pushing a code reference |
| 16 |
onto C<@{ $term->{selection_popup_hook} }>, which gets called whenever the |
| 17 |
popup is being displayed. |
| 18 |
|
| 19 |
Its sole argument is the popup menu, which can be modified. The selection |
| 20 |
is in C<$_>, which can be used to decide whether to add something or not. |
| 21 |
It should either return nothing or a string and a code reference. The |
| 22 |
string will be used as button text and the code reference will be called |
| 23 |
when the button gets activated and should transform C<$_>. |
| 24 |
|
| 25 |
The following will add an entry C<a to b> that transforms all C<a>s in |
| 26 |
the selection to C<b>s, but only if the selection currently contains any |
| 27 |
C<a>s: |

/a/ ? ("a to b" => sub { s/a/b/g } |
