External Canto

Here is a Canto link_handler that opens the feed item in the most recently focused uzbl-browser:

In your Canto config:

link_handler("echo \"uri %u\" > `cat $XDG_CACHE_HOME/uzbl/uzbl_in_focus_fifo`")

In your Uzbl config:

@on_event FOCUS_GAINED sh 'echo "$4" >$XDG_CACHE_HOME/uzbl/uzbl_in_focus_fifo'
