-match. To abort without selecting any match either use "q".
+match (underlined by default). To abort without selecting any match use "q".
To change the selection mode (e.g. paths, files, etc.) use one of the mappings
explained below. Per default URLs are selected, see options for a way to
change this.
+I<NOTE>: Opening URLs in the browser passes the URL via the command line which
+leaks URLs to other users on the current system via C<ps aux> or C<top>.
+
I<NOTE>: When yanking (copying) a temporary file is used to pass the data to
GNU screen/Tmux without exposing it to C<ps aux> or C<top>. However this may
leak data if those temporary files are written to disk. To prevent this change
