Get Archive per Geoffrey De Belie

Retrieve a dead link from an archive service with these shortcuts:
* CTRL+3: get an archive.org link (Wayback Machine) and copy the archive link to the clipboard
* CTRL+4: get an archive.is link and copy the archive link to the clipboard
* CTRL+5: get an webcitation.org link and copy the archive link to the clipboard
* CTRL+6: retrieve the current page from Google Cache

If you want to get an archive link for a page that no longer exists, either:
* right click the dead link and select the appropriate option
* press CTRL+3, CTRL+4, CTRL+5 and CTRL+6 on the talk page with only one link (works on wiki talk pages only that use MediaWiki)
* right click on the page you want to restore and select the option you wish
