// first, it needs to be loaded before every time it is used.
-// One way would be to use something like load_start_handler to send
-// "act script /usr/share/examples/scripts/linkfollow.js"
-// (currently, it is recommended to use load_finish_handler since the JS code seems to get
-// flushed. Using a load_start_handler with a 1s delay works but not always)
+// One way would be to use the load_commit_handler:
+// set load_commit_handler = sh 'echo "script /usr/share/uzbl/examples/scripts/linkfollow.js" > "$4"'
//
// when script is loaded, it can be invoked with
-// bind f* = js hints.set("%s")
-// bind f_ = js hints.follow("%s")
+// bind f* = js hints.set("%s", hints.open)
+// bind f_ = js hints.follow("%s",hints.open)
//
// At the moment, it may be useful to have way of forcing uzbl to load the script
-// bind :lf = script /usr/share/examples/scripts/linkfollow.js
+// bind :lf = script /usr/share/uzbl/examples/scripts/linkfollow.js
//
-// To enable hint highlighting, add:
+// The default style for the hints are pretty ugly, so it is recommended to add the following
+// to config file
// set stylesheet_uri = /usr/share/uzbl/examples/data/style.css
//
// based on follow_Numbers.js
//
// TODO: fix styling for the first element
-// TODO: load the script as soon as the DOM is ready
+// TODO: emulate mouseover events when visiting some elements
+// TODO: rewrite the element->action handling
