selection-popup - selection management pop-up |

|

=head1 DESCRIPTION |
| 10 |
|
| 11 |
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 |
|
| 16 |
Other extensions can extend this popup menu by pushing a code reference |
| 17 |
onto C<< @{ $term->{selection_popup_hook} } >>, which gets called whenever |
| 18 |
the popup is being displayed. |
| 19 |
|
| 20 |
Its sole argument is the popup menu, which can be modified. The selection |
| 21 |
is in C<$_>, 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: |
